List of spells

The following is a list of known spells employed by the wizarding world.

Accio (Summoning Charm)

 * Pronunciation: Although (AK-ee-o) is the proper Latin pronunciation and is used in the film, it has also been pronounced (A-see-o) and (AK-see-o).
 * Accio.jpg
 * Description: This charm summons an object to the caster, potentially over a significant distance. It can be used in two ways; either by casting the charm and then naming the object desired, or by pointing your wand at the desired object during or immediately following the incantation to "pull" the target toward the caster; in either case, the caster must concentrate on the object they wish to summon in order for the charm to succeed. The caster doesn't necessarily need to know the location of the target if they say the name of the object to be summoned, such as when a sixth year student summoned some books from her deceased headmaster's office simply by saying "Accio Horcrux books!" while in Gryffindor Tower.
 * Seen/Mentioned: Harry Potter summoned his broom to complete the first task of the Triwizard Tournament in 1994, as well as to summon the Portkey to escape his enemy and the Death Eaters in the Little Hangleton Graveyard in 1995.
 * Notes: The summoning charm is limited only to items and small animals, as it was shown to be incapable of summoning people; it is also possible to bewitch items to become impervious to this spell.
 * Etymology: The Latin word accio means "I call" or "I summon".

Age Line

 * Description: Creates a thin, shimmering golden line around the target that is impassable by those below a set age. It seems that ageing potions are useless against the line, and it appears that the lines functions on either calendar or mental age.

 * Seen/Mentioned: Used by Fleur Delacour in 1994 to extinguish her skirt, which had caught flame during a fight against a dragon. Harry used this spell twice in 1997, both on the same night; once to attempt to provide a drink for Dumbledore, then again to help douse Hagrid's hut after it was set aflame by Thorfinn Rowle, who used the Fire-Making Spell.
 * Etymology: Possibly a hybrid of Latin words aqua, which means "water", and mentis, which means "mind".

 * Etymology: The incantation is derived from the West African Sidiki dialect used in geomancy; it means "friendly to thieves", as stated by tje author in testimony during a court case.
 * Notes: Whilst in the first book, when the spell is cast the lock or dor must be tapped once, in the fifth, a healer simply points her wand at the door to cast it, and on an official site the wand motion is seen as a backward 'S'.

Anapneo

 * Pronunciation: ah-NAP-nee-oh
 * Description: Clears the target's airway, should they find it blocked.
 * Seen/Mentioned: Used only by Horace Slughorn, cast upon Marcus Belby when the latter choked on a pheasant in 1996.

Harry uses this spell in a forest to defend he and his friend from some spiders that are attacking them. He learned the spell from Tom Riddle's invitation to Harry to take him back 50 years for more imformation about the Chamber of Secrets.

Avada Kedavra (Killing Curse)

 * Pronunciation: ah-VAH-dah keh-DAV-rah
 * Description: Causes instant death to the victim, is accompanied by a flash of green light and a rushing noise; there is no known counter-curse, although there are a number of ways to prevent death by it, such as hitting it with another spell in mid-flight, dodging it, or interrupting the caster. It is one of three curses whose use results in a life sentence in jail.
 * Harry Potter was saved from this spell a number of times, both by his mother's sacrifice, because he was an accidental horcrux, and because his wand and his enemy's were made of the same core.
 * Seen/Mentioned: First said (not by name) in 1991, during the flashback while Hagrid described his parents' deaths to Harry; next, the first part of the incantation was said by Lucius Malfoy when he tried to kill Harry, and numerous times in every book following.
 * Etymology: During an audience interview at the Edinburgh Book Festival on 15 April, 2004 J. K. Rowling said "Does anyone know where avada kedavra came from? It is an ancient spell in Aramaic, and it is the original of abracadabra, which means "let the thing be destroyed". Originally, it was used to cure illness and the "thing" was the illness, but I decided to make the "thing" as in the person standing in front of me. I take a lot of liberties with things like that. I twist them round and make them mine."

Avifors

 * Pronunciation: AVI-forz
 * Description: Transforms the target into a bird
 * Seen/Mentioned: Used multiple times throughout the video games.

Bat-Bogey Hex

 * Description: It is another spell that is not fully understood, but most people presume, based on clues from the text, that it grotesquely enlarges the target's bogies, gives them wings, and sets them attacking the target.
 * Seen/Mentioned: Ginny Weasley was a noted practitioner of this spell, having used it at least thrice by her sixth year.
 * Notes: This spell may be related to, or the same as, the Curse of the Bogies mentioned in 1991; however, that spell gives the victim a runny nose, and hence the two may be different.

Engorgio Skullus

 * Pronunciation: in-GORE-jee-oh SKUH-las

Episkey

 * Seen/Mentioned: Taught to Harry by Professor Lupin; Harry later taught Dumbledore's Army this charm. This is the only spell effective against Lethifolds.

 * Seen/Mentioned: Used by Cho Chang in 1995 on her friend.

Expulso

 * Pronunciation: ecks-PUHL-soh

 * Etymology: Latin fidelis, which means "faithful".
 * Notes: Although the author had previously explained that when a Secret-Keeper dies the secret they held can never be revealed to anyone else, in 1997 it is clearly explained that upon the Keeper's death all those who had been told the secret become keepers in turn.
 * Notes (2): This charm seems to have no effect with regard to animals, as Hedwig found Ron and Hermione in a location that was protected by this charm; however, it is possible that Dumbledore somehow told her, ludicrous though such may seem.
 * Notes (3): In 1981, Hagrid managed to get to Harry before all the Muggles could look at it; this makes it appear as though the Killing Curse will negate the effect of the Fidelius Charm.
 * Notes (4): Those who have been told of the secret by secret-keepers still cannot pass the secret on, as proven by Severus Snape and Bellatrix Lestrange.

Fiendfyre

 * Description: Creates great spirits of fire which burn anything in its path, including nearly indistructable substances such as horcruxes. This fire is nearly impossible to control.

 * Description: Reveals human presence in the vicinity of the caster.
 * Seen/Mentioned: Used multiple times by various people in 1997.

(Horcrux Curse)

 * Description: This spell allows a part of a wizard's soul to pass into an object, thereby making the object a Horcrux. One has to commit murder and take advantage of the soul's "splitting apart" by this supreme act of evil in order to be able to perform this spell, and it is probably very complex. In 1943, Horace Slughorn described the spell to a young Tom Riddle as encasing a portion of the torn soul and placing it within an object. The spell itself is described in detail in a banned book known as "Secret of the Darkest Art", which Hermione Granger summoned from Albus Dumbledore's office near the end of their sixth year.  According to the text, use of this spell to separate the soul will make the remaining portion of the soul very fragile, and can only be reversed by "remorse" of the wrongs the creator had made; however, the pain caused by attempting to reverse the creation of a Horcrux can destroy the individual.
 * Seen/Mentioned: Used by Lord Voldemort while creating his Horcruxes.
 * Notes: When J.K.Rowling was asked about what the steps are to create a Horcrux Rowling declined to answer, saying that "some things are better left unsaid". However, in the Harry Potter Encyclopedia, it is explained, and the editor is said to have felt like vomiting after reading it.

 * Seen/Mentioned: Used by Hermione Granger in 1995 to dry off her robes. Also used shortly after to melt snow. Also was used by Albus Dumbledore in 1997 to dry Harry's and his own robes. Quite possibly a form of Ventus.

 * Seen/Mentioned: Used by Dobby to levitate a cake.

(Hurling Hex)

 * Description: Causes brooms to vibrate violently in the air and try to buck their rider off.

 * Description: Renders living targets immobile.
 * Seen/Mentioned: Hermione used it 1992 to freeze 2 Cornish Pixies. According to Horace Slughorn, a Freezing Charm will disable a Muggle Burglar Alarm. It strikes resemblances to the Flame-Freezing Charm, which negates the effects of fire.

 * Etymology: Latin impedimentum (plural impedimenta), "a hindrance" or "an impediment".

Imperio (Imperius Curse)

 * Pronunciation: im-PEER-ee-oh
 * Description: One of the three "Unforgivable Curses". Places the subject in a dream-like state, in which he or she is utterly subject to the will of the caster.

 * Seen/Mentioned: Used on many occasions. First seen in 1994 when Barty Crouch Jr, impersonating ex-Auror Alastor Moody, used it on a spider and later on students during a "class demonstration" in a Defence Against the Dark Arts class.

 * Etymology: It is said that the Latin impervius means (and is the source of) "impervious"; although it is the source of the word, it is better translated as impassable, as in a mountain peak.

 * Pronunciation: in-an-ih-MAH-tus CON-jur-us
 * Description: It is a spell of unknown effect, most likely used to conjure an inanimate object.
 * Seen/Mentioned: Mentioned briefly in 1995.

Incarcerous

 * Pronunciation: in-CAR-ser-us

 * Seen/Mentioned: First heard in 1996, when Dolores Umbridge tries to hold off Centaurs. Also used by Harry on the Inferi in Voldemort's Horcrux cave in 1997.
 * Etymology: Probably English incarcerate, "to imprison". Possibly linked to the Latin in carcerem, "in(to) prison".
 * Notes: A non-verbal version of this spell may have been used to tie up Remus Lupin by Severus Snape during the encounter in the Shrieking Shack, and then later Peter Pettigrew in 1994. It may also have been used by Quirrell in 1992, although he is said to have merely "snapped his fingers".

 * Description: Produces fire.
 * Seen/Mentioned: It was first seen in 1994 by Arthur Weasley to create a fire in the Dursleys' hearth so that he could use Floo powder there. In 1997, this spell was used several times in battle, most noticeably when Hagrid's hut was set ablaze. It was also possibly used by Hagrid in 1991 to create a fire in the hearth before bringing Harry to London.
 * Etymology: Latin incendere, "to set fire (to)". Note that the first principal part of this verb (meaning "I set fire") is incendo, not incendio; Rowling's incantation does not match exactly any correct conjugation of the verb. Incêndio, in Portuguese (same pronunciation as in English) means 'huge fire'. "Encender" in Spanish means "to ignite" and "Incendie" in French means flame. (A plausible but less likely source might be that it is a back-formation from the English word "incendiary," i.e., "causing fire.")
 * Notes: Probably the charm used frequently by Hermione, as it is noted that creating small portable fires is a speciality of hers. This fire is said to be portable and blue, which may be a different enchanted fire, possibly the bluebells flames incantation.

Inflatus

 * Pronunciation: in-FLAY-tus
 * Description: Inflates objects (living or dead).
 * Seen/Mentioned: One of the secondary spells in Harry Potter and the Goblet of Fire (video game)

 * Seen/Mentioned: During the September 1999 riot that took place during the Puddlemere United/Holyhead Harpies Quidditch game, a lot of Harpy supporters were using this jinx.

 * Description: The victim is dangled upside-down by their ankles, sometimes accompanied by a flash of light (this may be a variant of the spell).
 * Seen/Mentioned: Apparently invented by the Half-Blood Prince; it is a non-verbal-only spell (although it is whispered by Hermione in 1997). Harry Potter learnt it by reading the notes written by the Half-Blood Prince. He used it on Ron. The previous year, Harry had seen (through the Pensieve used by Severus Snape) his father, James Potter, use the spell against Professor Snape. In the Order of the Phoenix film, Luna Lovegood somehow uses this against a Death Eater, although she speaks it, and the spell's name is unknown to any students until Half-Blood Prince.

 * Etymology: Latin liberare, "to free", and corpus, "body".

A variation seen in 1998 is Piertotum Locomotor, which caused the statues of Hogwarts to be animated.

http://images3.wikia.nocookie.net/__cb20110924121358/harrypotter/images/9/95/Leg-locker-curse.png
 * Description: Locks the legs together, preventing the victim from moving the legs in any fashion.
 * Seen/Mentioned: Used by Draco Malfoy on Neville Longbottom in 1991. Used by Harry Potter on Draco Malfoy, who deflected it, in 1996. One of the spells on Pottermore.
 * Etymology: English locomotion, "movement" + Latin mortis, "of death".
 * Notes: It is unclear whether or how this spell is related to the Locomotor spell. It could, however, be that the curse "locks" any part of the body in accordance to where it is pointed, or moves the body into a position of the caster's choosing whilst placing them into an immobile state. It is possible that Draco had pointed his wand at Neville and the curse "locked" his legs together.
 * Notes (2): It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.

Lumos

 * Pronunciation: LOO-mos
 * Wand Motion:

http://images3.wikia.nocookie.net/__cb20110924144857/harrypotter/images/c/c7/Wand-lighting-charm.png
 * Description: Creates a narrow beam of light that shines from the wand's tip, like a torch.
 * Seen/Mentioned: Constantly throughout the series. A stronger version of this spell, Lumos Maxima is performed by Harry Potter at the Dursleys' house in the film adaptation of Harry Potter and the Prisoner of Azkaban, and by both Harry and Dumbledore in the Horcrux cave in the film adaptation of Harry Potter and the Half-Blood Prince. Used in Pottermore.
 * Etymology: Latin lumen, "light".
 * Notes: opposite incantation, Nox, puts the light out.

Lumos Duo

 * Pronunciation: LOO-mos DOO-oh
 * Description: Creates an intense beam of light that projects from the wand's tip and can lock-on to various targets, turn hinkypunks solid and cause ghouls to retreat.
 * Seen/Mentioned: Learned and used by Ron in the video game adaptation of Harry Potter and the Prisoner of Azkaban.
 * Etymology: Lumos plus Latin duo, "two".

Lumos Solem

 * Pronunciation: LOO-mos SO-lem
 * Description: Creates a powerful ray of light as bright as the sun.
 * Seen/Mentioned: Used by Hermione to free Ron from the Devil's Snare. The incantation was only used in the film adaptation of Harry Potter and the Philosopher's Stone.
 * Etymology: Derived from two words; the Latin lumen, meaning "light", and the Latin word for "sun", which in its accusative case is "solem".
 * Notes: It is possible that the quality of the light is on the warmer solar end of the spectrum; Considering the known uses that the spell has been put to, it isn't that much of a stretch to presume that the spell is used to conjure Sunlight.

Lumos Maxima
 * Pronunciation: LOO-mos Ma-cks-ima
 * Description: Shoots a ball of light at the place pointed, if the Wand is swung.
 * Seen/Mentioned: First practiced by Harry in the home of the Dursleys, then used by Dumbledore to light up the cave of the Horcrux.
 * Etymology: Lumos + maxima, Latin "greatest."

Melofors

 * Description: Encases the target's head in a pumpkin.
 * Seen/Mentioned: PoA game, GoF game, Harry Potter and the Order of the Phoenix, LEGO Harry Potter: Years 1-4/5-7.

Meteolojinx Recanto

 * Pronunciation: mee-tee-OH-loh-jinks reh-CAN-toh.
 * Description: Presumably causes weather effects caused by jinxes to cease.
 * Seen/Mentioned: Suggested in 1997 by Arthur Weasley to Ron (disguised as Reginald Cattermole by use of Polyjuice Potion) as the best way to clear up the rain jinx on a Ministry office. Also used by Bartemius Crouch Jr. (Disguised as Alastor Moody) In 1994 to cease the weather effect of the Great Hall's Ceiling insisting it is broken as he told Dumbledore to "Fix his ceiling".
 * Etymology: Meteorology, the study of weather, the word jinx and recant, "to withdraw or retract". Interestingly in modern English recant means to say that you no longer hold a belief.

Mimblewimble (Tongue-Tying Curse)

 * Pronunciation: MIM-bull-WIM-bull
 * Wand Motion:

http://images4.wikia.nocookie.net/__cb20110924120542/harrypotter/images/c/cf/Tongue-tying-curse.png
 * Description: A curse which prevents certain information from being revealed by the individual upon whom the spell is placed. The curse manifests itself by causing the tongue to temporarily curl backwards upon itself.
 * Seen/Mentioned: Seen in 1997 as a deterrent to Severus Snape, or any other unwanted visitor of 12 Grimmauld Place, from betraying their location to anyone else.

Mobiliarbus

 * Pronunciation: MO-bil-ee-AR-bus
 * Description: Levitates and moves an object.
 * Seen/Mentioned: In 1993, Hermione Granger used the spell to move a Christmas Tree in The Three Broomsticks beside her table to hide Harry Potter, who was in Hogsmeade illegally.
 * Etymology: Latin mobilis, "movable" or "flexible", and arbor (alternatively arbos), "tree".
 * Notes: It is possible that Mobilicorpus and Mobiliarbus are variations of the same basic spell, since they share the "Mobili-" stem.

Mobilicorpus

 * Pronunciation: MO-bil-ee-COR-pus
 * Description: Levitates and moves bodies.
 * Seen/Mentioned: Sirius Black used it on Severus Snape in 1994. It was probably used on Peter Pettigrew by Lord Voldemort in the graveyard to make him come forward.
 * Etymology: Latin mobilis, "movable", and corpus, "body".
 * Notes: It is possible that Mobiliarbus and Mobilicorpus are variations of the same basic spell, since they share the "Mobili-" stem.

Molly Weasley's Curse

 * Pronunciation: Unknown
 * Description: Like the Avada Kedavra curse, it kills (or freezes) the victim. It turns the body gray/blue (or paler) while it turns to stone and then another twin jinx can blast the body into pieces.
 * Seen/Mentioned: Molly Weasley used the curse after Bellatrix Lestrange attacked Ginny Weasley. Only used in the film version.
 * Notes: This may be Duro or a Freezing Charm, although the latter is shown to be blue in 1992.

Morsmordre (Dark Mark)

 * Pronunciation: morz-MOR-duh, morz-MOHR-dah, morz-MOR-drah
 * Description: Conjures the Dark Mark.
 * Seen/Mentioned: Used by Barty Crouch Jr in 1994. Also seen in 1997 over the castle to lure Albus Dumbledore to his death. It was apparently invented by Lord Voldemort.
 * Etymology: Latin mors, "death", and mordere, meaning "to bite" (or its French derivative mordre); this would appear to be associated with the name of Lord Voldemort's followers, the Death Eaters. The English murder might also contribute.
 * Notes: A possible translation might be "take a bite out of death", a fitting phrase for Death Eaters.

Muffliato

 * Pronunciation: muf-lee-AH-to
 * Description: This spell fills peoples' ears with an unidentifiable buzzing to keep them from hearing nearby conversations.
 * Seen/Mentioned: It was used in 1996 by Harry Potter and Ron Weasley on various teachers and people such as Madam Pomfrey. It was created by Severus Snape. As pointed out by Hermione, it is probably not Ministry of Magic approved. It was also used in 1997 by Hermione Granger in protection of the camp-site where Harry and she stayed in hiding.
 * Etymology: English muffle, "to quiet", with a pseudo-Latin or pseudo-Italian ending.

Multicorfors

 * Pronunciation: mull-tee-COR-fors
 * Description: Multicorfors is a charm used to change the colour of one's clothing.
 * Seen/Mentioned: It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4. It may also be the same charm as when Harry accidentally changed the colour of his eyebrow, before he asked Luna to Slughorn's Christmas party. (Unlikely, as that was performed as a Transfiguration exercise, which is rather unrelated to Charms.) Could have possibly been used when Harry accidentally changed the colour of his teachers hair, in his Primary School.

Nox

 * Pronunciation: Nocks
 * Wand Motion:

http://images1.wikia.nocookie.net/__cb20110924144616/harrypotter/images/c/c1/Wand-extinguishing-charm.png
 * Description: Turns off the light produced by Lumos.
 * Seen/Mentioned: In 1994, Harry Potter and Hermione Granger used this spell to turn off their wand-lights in the Shrieking Shack.  Used in 1998 when Harry was in the passage beneath the Whomping Willow which leads to the Shrieking Shack. Lumos's power can be arranged so that a powerful wizard can make the charm illuminate intensely or to the wizards liking by loudness of incantation. For example "LUMOS!!!" would be powerful and "lumos" would be weaker. Also used by Harry Potter in 1998 to turn off the light so he could hide the Marauder's Map from Severus Snape.
 * Etymology: Latin nox, meaning "night".

Oculus Reparo

 * Description: Mends eyeglasses.
 * Seen/Mentioned: Used by Hermione in 1991 and 1992 to fix Harry's glasses.
 * Notes: This spell is a variation of Reparo.

(Obliteration Charm)

 * Description: Removes footprints.
 * Seen/Mentioned: Used by Hermione in 1995 to remove the footprints that she, Harry, and Ron left in the snow while walking to Hagrid's hut. Also used in 1997 by Hermione to remove the footprints she and Harry left behind them in the snow as they journeyed through Godric's Hollow.
 * Notes: The above instance in book five only reveals that the Obliteration Charm can remove footprints. There is no explanation as to what effect it can have on other things. It could possibly destroy things, according to its name.

Obliviate (Memory Charm)

 * Pronunciation: oh-BLI-vee-ate
 * Wand Motion:

http://images1.wikia.nocookie.net/__cb20120711184458/harrypotter/images/9/9f/Memory-charm.png
 * Description: Used to hide a memory of a particular event.
 * Seen/Mentioned: First seen in 1993 when used by Gilderoy Lockhart on Harry and Ron; the spell backfired due to a faulty wand, costing Lockhart most of his own memory. Also, Hermione Granger used this spell to wipe her parents memories in 1997. Again, it was used in 1997 when Hermione Granger used the spell on 2 Death Eaters who had followed Harry, Ron, and Hermione after their escape from Bill Weasley's and Fleur Delacour's wedding.
 * Etymology: Latin oblivisci, "forget". The spell is most often used against Muggles who have seen something of the Wizarding world.
 * Notes: Memory Charms are confirmed on J.K. Rowling's website to have been developed by a witch named Mnemone Radford, who became the Ministry's first Obliviator. The Ministry of Magic employees assigned to modifying the memories of Muggles are called Obliviators. The charm can be broken by powerful magic, or extreme duress, as Lord Voldemort was able to torture Bertha Jorkins into remembering details that Barty Crouch Sr had forced her to forget using the charm. In this case, it was also shown that if the charm is too powerful, it can cause the target to develop a bad memory. This spell differs from the False Memory Charm.

Obscuro

 * Pronunciation: ob-SK(Y)OOR-oh
 * Description: Causes a blindfold to appear over the victim's eyes, obstructing their view of their surroundings.
 * Seen/Mentioned: Used by Hermione Granger in 1997 to obstruct the portrait of Phineas Nigellus's view of their location.

Oppugno

 * Pronunciation: oh-PUG-noh
 * Description: Apparently causes animals or beings of lesser intelligence to attack.
 * Seen/Mentioned: Used by Hermione Granger in 1996 to attack Ron Weasley with a summoned flock of canaries during an argument.
 * Etymology: Latin oppugno, "I attack".

Orbis

 * Pronunciation: OR-biss
 * Description: Sucks the target into the ground
 * Seen/Mentioned: Used multiple times in 1993.
 * Etymology: Orbis is Latin for 'circle', which reflects the spell's physical appearence.

Orchideous

 * Pronunciation: or-KID-ee-us
 * Description: Makes a bouquet of flowers appear out of the caster's wand.
 * Seen/Mentioned: Used in 1994 by Mr. Ollivander to test Fleur Delacour's wand. Probably used non-verbally by Tom Riddle to present flowers to Mrs. Smith.
 * Etymology: English orchid and Latin suffix -eous, "of or bearing (the root word)".
 * Notes: A variation of this spell may have been used when Hermione Granger conjured a Christmas wreath to place on James and Lily Potter's graves in 1997.

Pack

 * Pronunciation: pak
 * Description: Packs a trunk, or perhaps any luggage.
 * Seen/Mentioned: Used in Harry Potter and the Prisoner of Azkaban by Remus Lupin in his office, and in Harry Potter and the Order of the Phoenix by Nymphadora Tonks, once verbally and again non-verbally.

(Patented Daydream Charm)

 * Pronunciation: Unknown
 * Description: Gives the spell caster a highly-realistic 30-minute daydream. Side effects include mild drooling and a vacant expression.
 * Seen/Mentioned: These were invented by Fred and George Weasley and sold in 1996 at their joke shop, presumably in the form of some kind of physical object, similar to Skiving Snackboxes.

Partis Temporus

 * Pronunciation: par-tís temp-oar-us
 * Description: Creates a temporary gap through protective magical barriers.
 * Seen/Mentioned: Used by Albus Dumbledore in the Horcrux cave in the film version of Harry Potter and the Half-Blood Prince. He uses it so that he and Harry can pass through the ring of fire used to ward off the Inferi.
 * Etymology: Partis is a plural form of the French verb partir, which means "to separate," "to go away," "to leave," or "to depart." Temporis is Latin for "time."

Periculum

 * Pronunciation: pur-ick-you-lum
 * Wand Motion:

http://images4.wikia.nocookie.net/__cb20110924144225/harrypotter/images/f/f1/Red-sparks.png
 * Description: Creates red sparks/flares to shoot from the users wand
 * Seen/Mentioned: Used during the third task of the Tri-wizard Tournament by Harry. Also believed to have been used in Pottermore, but is called the "Red Sparks Spell".

(Permanent Sticking Charm)

 * Description: Makes objects permanently stay in place.
 * Seen/Mentioned: First mentioned in 1995, when Sirius Black suspected that his mother's painting was fixed to the wall with such a Charm. It is implied that the portrait in the Muggle Prime Minister's office also has such a charm on it.
 * Notes: It is never said whether the charm prevents the object from being removed by cutting away the section of wall. The incantation could be gluten sempra, meaning glue forever, or adher sempra, which means stick forever.

Peskipiksi Pesternomi

 * Pronunciation: PES-key PIX-ee PES-ter NO-mee
 * Description: The one time it was used, it had absolutely no effect.
 * Seen/Mentioned: Used by Lockhart to attempt to remove Cornish Pixies.
 * Suggested Etymology: English pesky meaning "annoying", English pixie meaning "a supernatural being", English pester meaning "to annoy", English no for negative and English me for the first person pronoun.
 * Notes: It is not known if the spell works or not. It also suspiciously sounds like "Pesky pixie pester no me."

Petrificus Totalus (Full Body-Bind Curse)

 * Pronunciation: pe-TRI-fi-cus to-TAH-lus
 * Wand Motion:

http://images1.wikia.nocookie.net/__cb20110924142134/harrypotter/images/9/9b/Full-body-bind.png
 * Description: Used to temporarily bind the victim's body in a position much like that of a soldier at attention; the victim will usually fall to the ground.
 * Seen/Mentioned: First used in 1991 by Hermione, who was trying to prevent Neville from stopping her, Ron, and Harry from leaving the common room to hunt for the Philosopher's Stone. Also used in the Hall of Prophecy in the film adaptation of Harry Potter and the Order of the Phoenix to petrify one of the Death Eaters pursuing the group. Also used on Harry by Draco Malfoy in the train in Harry Potter and the Half-Blood Prince. Used also in Pottermore.
 * Etymology: Latin petra, meaning "stone", and fieri (past participle factus), meaning "to become"; totalus comes from Latin "totus", meaning "complete".
 * Note: Albus Dumbledore used Petrificus Totalus on Harry during the first Battle of Hogwarts while Draco Malfoy disarmed him.

Piertotum Locomotor

 * Pronunciation: pee-ayr-TOH-tum (or peer-TOH-tum) loh-koh-MOH-tor
 * Description: Spell used to animate statues and suits of armour to do the caster's bidding.
 * Seen/Mentioned: In the Battle of Hogwarts, Professor McGonagall used this spell to animate the suits of armour and statues within Hogwarts, to defend the castle. Possibly used by Albus Dumbledore to enchant the statues on the fountain in the entrance to the Ministry of Magic Department.
 * Etymology: Pier means "friend" or "colleague", totum refers to "the whole" or "total", and locomotor means "the movement of".

(Placement Charm)

 * Description: A charm which temporarily places an object upon a desired target.
 * Seen/Mentioned: Mentioned in Fantastic Beasts and Where to Find Them.

Point Me (Four-Point Spell)

 * Pronunciation: English phrase
 * Description: Causes the caster's wand to act as a compass, and point North.
 * Seen/Mentioned: Hermione Granger taught it to Harry Potter, who used it during the Triwizard Tournament, particularly to navigate the hedge maze during the Third Task.
 * Note: This spell may be an invention of Hermione Granger; it is unclear in the Goblet of Fire text whether she invented it herself or found it through research. Given that the incantation is English (whereas almost all other mentioned spells have incantations based on Latin or other old languages) and that none of the other champions of the Tournament seem to use the spell, it seems likely that Hermione invented the spell.

Portus

 * Pronunciation: POR-tus
 * Description: Turns an object into a port-key
 * Seen/Mentioned: Used by Albus Dumbledore in 1996.
 * Etymology: Latin porta, meaning "gate", or portare, meaning "to carry" (as in to carry the caster or target to another location). There is a Latin word portus, meaning "harbour", but it is inappropriate in this context.
 * Notes: Portkeys were first seen in 1994 as a means for Harry, Hermione, and the Weasleys to go to the Quidditch World Cup. However, the spell used in its creation was not seen until 1995.

Priori Incantato

 * Pronunciation: pri-OR in-can-TAH-toh
 * Description: Causes the echo (a shadow or image) of the last spell cast by a wand to emanate from it.
 * Seen/Mentioned: Used by Amos Diggory in 1994 to discover the last spell cast by Harry's wand after it was found in the hands of Winky, a house-elf.
 * Etymology: Latin prior, "previous", and incantare, "to speak a spell" (past participle incantatum).
 * Notes: The nature of the "echo" depends on the original spell. The echo of a conjuring spell, for example, is the object conjured; the echo of the Cruciatus Curse is the screaming of the victim; the echo of an Avada Kedavra curse is the image of its victim.
 * Notes(2): Amos Diggory used this spell to find out if Harry's wand (held by Winky, Bartemius Crouch's house elf) cast the Dark Mark.
 * Notes(3): Apparently the spell is cumulative, with the user able to go further back and see spells that the wand performed after the latest spell. Harry suggests this in 1997. Hermione does not contradict his claim, suggesting this is true.

(Protean Charm)

 * Description: Causes copies of an object to be remotely affected by changes made to the original.
 * Seen/Mentioned: First used in 1995. Hermione Granger put the charm on a number of fake Galleons. Instead of the serial number around the edge of the coin, the time and date of the next meeting of Dumbledore's Army appeared. It is possible that this charm is used on the Death Eaters' Dark Marks.
 * Etymology: The English word Protean derives from Proteus, a god in Greek Mythology. Proteus was a shape-shifter, able to take many forms. As a result, the word Protean has come to refer to versatility, flexibility, or an ability to assume many forms. "Protean" is also similar to "protein", derived from the same root, meaning a variable, flexible substance which forms strong bonds between its constituent parts.
 * Notes: On Hermione's fake galleons, when the date changes, the coin becomes hot, alerting the owner to look at the coin. This may not be a feature of the original charm. It may be a Flagrante Curse, when the Protean Charm changes the coin the curse may activate. It would seem from this that you can decide what the effects on the charmed objects are. Possibly by saying something along the lines of "Protean flagrante." although this is just speculation
 * Notes (2): The Protean Charm is a N.E.W.T. standard charm, according to Terry Boot, who is incredulous that Hermione can perform the spell even though she is only in her fifth year (N.E.W.T.s are taken in the seventh year at Hogwarts).

Protego (Shield Charm)

 * Pronunciation: pro-TAY-goh
 * pro-te-goh
 * Description: The Shield Charm causes minor to moderate jinxes, curses, and hexes to rebound upon the attacker.
 * Seen/Mentioned: First seen in 1995, in which Harry is taught this spell by Hermione in preparation for the third task in the Triwizard Tournament. Albus Dumbledore uses a similar spell which reverses the construction of glass back into sand when Voldemort sent shards of glass to try to stab Dumbledore. Fred and George Weasley enchanted hats they dubbed "shield hats" with this spell in 1997.
 * Etymology: Latin protego, "I cover" or "I protect".
 * Notes: The original description of this spell states that it rebounds minor jinxes to the caster. However, it is shown in the books that it can also be used to reflect or lessen the effects of more powerful spells, depending on the skill of the caster. In 1998, it is also shown to be able to create a sort of force-field across an area, and is used frequently to prevent two participants in an argument from reaching each other.

Protego Horribilis

 * Pronunciation: pro-TAY-goh horr-uh-BIHL-ihs
 * Description: A powerful shield charm against dark magic.
 * Seen/Mentioned: Cast by Professor Flitwick in an attempt to strengthen the castle's defences in the Battle of Hogwarts.

 * Pronunciation: KWIY-uh-tus
 * Description: Makes a magically magnified voice return to normal. A counter to Sonorus.
 * Seen/Mentioned: Used in 1994 by Ludo Bagman.
 * Etymology: Latin quietus, "calm" or "quiet".
 * Notes: It is conjectural whether Quietus could be used alone to magically quiet a person's voice, or only counteracts Sonorus.

Redactum Skullus

 * Pronunciation: red-AK-tum SKULL-us
 * Description: Redactum Skullus is a hex that shrinks the target's head. It is the counter-spell to ''Engorgio Skullus.
 * Seen/Mentioned: It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.

 * Seen/Mentioned: In Harry Potter and the Deathly Hallows: Part 1, Harry Potter, after checking his Blackthorn wand on the Bluebell flames with Engorgio, casts this spell to shorten the formerly enlarged flames.
 * Etymology: English reduce, "to shrink". (Latin has a verb reducere, present tense reduco. This is the source of the English "reduce", but has a different meaning.) Also in Italian Riduco first person present tense of Ridurre, same root of Latin Reducere.
 * Notes: Whether Reducio could also be used by itself rather than countering Engorgio is unknown. If it could, it would shrink normal sized items into miniature versions of themselves. References in 1992 by Arthur Weasley to "shrinking door keys" make this seem likely.

Reducto (Reductor Curse)

 * Pronunciation: re-DUK-toh
 * Description: Breaks objects. In stronger usages, disintegrates them.
 * Seen/Mentioned: In 1995, Harry used it on one of the hedges of the Triwizard maze and ends up burning a small hole in it; in 1995, Gryffindors in Harry Potter's year referenced Parvati Patil as being able to reduce a table full of Dark Detectors to ashes, and Harry and his friends later used the spell in the Department of Mysteries against the Death Eaters, shattering many Prophecy Orbs in the process; in 1997, a member of the Order of the Phoenix attempted to use this spell to break down a door which Death Eaters had blocked when the Death Eaters had cornered Dumbledore in the Lightning Struck Tower.
 * Etymology: English reduce, "to bring down;destroy".
 * Notes: Reparo makes a good counter-curse.

(Refilling Charm)

 * Description: Refills whatever the caster points at with the drink originally in the container.
 * Seen/Mentioned: Used in Harry Potter and the Half-Blood Prince, when Harry notices that Hagrid and Slughorn are running out of wine. This may have also been in the Harry Potter and the Deathly Hallows: Part 1 film as the water in the cups are shown refilling themselves.

(Reparifors)

 * Description: Reverts minor magically-induced ailments, such as paralysis and poisoning.
 * Seen/Mentioned: Harry Potter and the Prisoner of Azkaban (video game)

Relashio

 * Pronunciation: Re-LASH-ee-oh
 * Description: A spell used to make the subject release what ever it is holding or binding.
 * Seen/Mentioned: Used by Harry Potter against Grindylows in the second task of the Triwizard Tournament. Also used in 1997 and 1998, when Hermione used this spell to free Mrs. Cattermole from the chained chair and to free the Ukrainian Ironbelly on which they were to get out from Gringotts.]]
 * Etymology: Probably from the French verb relâcher ="to release, to set free", or Italian rilascio (pronounced the same way as the spell)= "I release".

Rennervate

 * Pronunciation: ree-nur-VAH-tay, REN-ur-vayt
 * Description: revives a stunned person.
 * Seen/Mentioned: In 1994, Amos Diggory used it to wake up Winky and Albus Dumbledore used it to wake up Viktor Krum. Harry Potter later used it to try and reawaken a cursed Dumbledore in the seaside cave.
 * Etymology: Officially renamed from Ennervate by J.K. Rowling. Rennervate means "to energize", whilst the former Ennervate, meant "to weaken,".

Reparifarge

 * Pronunciation: This information is currently unknown.
 * Description: Used to reverse unsuccessful transformations.
 * Seen/Mentioned: Seen only thus far in A Beginner's Guide to Transfiguration on Pottermore.
 * Etymology: This information is currently unknown.

Reparo

 * Pronunciation: reh-PAH-roh
 * Wand Motion:

http://images2.wikia.nocookie.net/__cb20110924150229/harrypotter/images/5/59/Mending-charm.png
 * Description: Used to repair objects.
 * Seen/Mentioned: Countless times throughout the books. Shattered objects are often described as having "flown" back together. However, substances contained in the broken objects don't get back inside. In 1995 Harry smashed a bowl of murtlap essence. He could repair the bowl but the murtlap essence remained splashed to the floor.
 * Etymology: Latin reparo meaning "to renew" or "repair".
 * Notes: This is the final spell used in the Harry Potter series. Reparo has been seen to repair non-magical items, however it seems to have an inability at repairing magical items or items that have magic placed upon them. An example is Harry's Nimbus 2000 shown in 1993 which he is told is irreparable after it is destroyed by the Whomping Willow. Wands are also irreparable, as shown in 1992 when Ron's wand snapped after he and Harry crashed onto the Hogwarts grounds. Despite his use of Spellotape, Ron's wand malfunctioned throughout the entire novel. Another example is in 1997 when Hermione tried to fix Harry's broken wand, which was snapped by her errant Blasting Curse. However, Harry repaired his wand with the Elder Wand. Since the Elder Wand is the most powerful wand in the universe, it makes sense that it would produce the most powerful Repairing Charm.

Repello Muggletum (Muggle-Repelling Charm)

 * Pronunciation: reh-PELL-loh MUG-ul-tum, MUGG-gleh-tum, mugg-GLEE-tum
 * Description: Keeps Muggles away from wizarding places by causing them to remember important meetings they missed and to cause the Muggles in question to forget what they were doing.
 * Seen/Mentioned: Mentioned in Quidditch Through the Ages as being used to keep Muggles away from the Quidditch World Cup. Hogwarts was also said to be guarded by the Muggle-Repelling Charm. It was also used by Harry and Hermione on numerous occasions, among many other spells, to protect and hide their camp site in 1997.

Repello Inimicum

 * Pronunciation: re-PEH-lloh ee-nee-MEE-cum
 * Description: Disintegrates the persons entering this charm.
 * Seen/Mentioned: This spell was used by professors Filius Flitwick and Horace Slughorn along with Order of the Phoenix member Molly Weasley to protect Hogwarts Castle in 1998.
 * Etymology: Latin "Repello", meaning "Push Back" and "inimicum", the accusative singular form of "inimīcus" meaning "foe" or "enemy".

Rictusempra (Tickling Charm)

 * Pronunciation: ric-tuhs-SEM-pra
 * Wand Motion:

http://images2.wikia.nocookie.net/__cb20120711184606/harrypotter/images/f/fc/Tickling-charm.png
 * Description: Causes an extreme tickling sensation that, in the case of Draco Malfoy, made him drop to the floor laughing.
 * Seen/Mentioned: By Harry Potter on Draco Malfoy in 1992, when they fought in the Duelling Club.
 * Etymology: Possibly the sum of two words; The Latin rictus, meaning "The expanse of an open mouth", and semper, meaning "Always". Rictus is generally used as an expression of terror, however, "always an open mouth" would, in most cases, correspond to the act of laughing uncontrollably.
 * Notes: It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.

Riddikulus (Boggart-Banishing Spell)

 * Pronunciation: rih-dih-KYU-lus
 * Description: A spell used when fighting a Boggart, "Riddikulus" forces the Boggart to take the appearance of an object the caster is focusing on. Best results can be achieved if the caster is focusing on something humorous, with the desire that laughter will weaken the Boggart.
 * Seen/Mentioned: First seen in 1993, when taught by Remus Lupin.
 * Etymology: Latin word ridiculus, "laughable" (but perhaps "absurd" or "silly" in this context).
 * Notes: The effect of the spell seems to rely primarily on the state of mind of the caster. It doesn't actually change the shape of a boggart into something humorous, but rather whatever the caster is concentrating on at the moment of the casting, as when Neville was thinking of his grandmother's dress. Presumably, Mrs. Weasley couldn't take her mind off of her fears for her family, so the Boggart was changed into other members of the family rather than something humorous.

(Rose Growth)

 * Description: Causes rosebushes grow at an unusually fast pace.
 * Seen/Mentioned: Harry Potter Trading Card Game
 * Notes: This spell may be related to Herbivicus.

(Rowboat spell)

 * Description: A spell invented by Hagrid which propels row boats to a pre-set destination.
 * Seen/mentioned: Hagrid used the spell on the row-boats at Hogwarts, to transport the First years from Hogsmeade Station to the Boathouse. It may also have been the spell that he used to propel the row-boat that he used to take Harry from the Hut-on-the-Rock back to the mainland in 1991.

Salvio Hexia

 * Pronunciation: SAL-vee-oh HECKS-ee-ah
 * Description: Unknown, as it was one of several spells that were used to help strengthen Harry's camp-site, and had no seen effects. Possibly deflects minor hexes aimed at an object (the tent)
 * Etymology: Possibly derived from the Latin "salveo," meaning "to be in good health," and used as a form of greeting and farewell, and a pseudo-Latin derivative of the English word "hex"—hence, "Farewell, hexes!"
 * Seen/Mentioned: Harry and Hermione cast this spell to strengthen their camp-site's defences against intruders in 1997.
 * Notes: Possibly the Hex Deflection spells the fake Moody mentioned in 1994.

Sardine hex

 * Pronunciation: Unknown
 * Description: Causes sardines to come out of the victim's nose.
 * Seen/Mentioned: Rubeus Hagrid once had this hex used on him.

Scourgify (Scouring Charm)

 * Pronunciation: SKUR-jih-fiy'''
 * Description: Used to clean something.
 * Seen/Mentioned: First used by Nymphadora Tonks to clean Hedwig's cage in 1995. Later, Ginny Weasley performed the spell to clean up the Stinksap on the Hogwarts Express, also used by James Potter on Severus Snape after he shouted various curses and obscenities at him.
 * Etymology: Perhaps related to English scour, "clean". -ify is a common English suffix meaning "to make ...". Therefore scourgify could mean "to make clean".

Sectumsempra

 * Pronunciation: sec-tum-SEMP-rah
 * Description: A dark spell that creates large, blood-oozing gashes on the subject as if said subject had been "slashed by a sword". Invented by Severus Snape.
 * Seen/Mentioned: Used by Harry in 1997 against Draco Malfoy, and then later against both the Inferi in Lord Voldemort's Horcrux chamber, and Snape used it against George Weasley (was unintentional; aimed for a Death Eater that tried to curse Lupin) in the Order's flight from Privet Drive. Harry learned it in Snape's old Potions textbook. In 1998, the spell is said to be Severus Snape's "signature" spell.
 * Etymology: Latin sectum, "cut", and semper, "always".
 * Notes: The spell can apparently be used against any object, but was not effective when used against Inferi because they could not bleed. The movement of the wand seems to affect how someone is cut, suggested by the erratic patterns of slashes left on Draco Malfoy's face and chest, produced by Harry Potter's wild wand-swings while using the spell against Draco. Wounds caused by this spell can be healed as proved by Severus Snape who after Harry hit Draco Malfoy with this spell he healed Draco's wounds and told him to go and get treated with dittany at once so that he would even avoid any sign of any wound. However it seems that it depends on the caster's magical abilities because Molly Weasley could not heal and restore George Weasley's ear that was cursed off by this spell.

Shield penetration spell

 * Pronunciation: unknown
 * Description: Presumably annihilates magical enchantments and shields.
 * Seen/Mentioned: Used by Voldemort to break the enchantments placed around Hogwarts School of Witchcraft and Wizardry in 1998 by Filius Flitwick, Minerva McGonagall, and Molly Weasley.
 * Etymology: unknown

Smokescreen Spell

 * Wand Motion:

http://images3.wikia.nocookie.net/__cb20110924144347/harrypotter/images/d/dc/Smokescreen-spell.png
 * Description:' Produces a defensive cloud of smoke from the wand tip; the incantation is believed to be Fumos because of the similarities between the two spells.
 * Seen/Mentioned: Used on Pottermore.
 * Notes: This is probably Fumos or a variant thereof.

Serpensortia

 * Pronunciation: ser-pen-SOR-shah, SER-pehn-SOR-tee-ah
 * Description: Conjures a serpent from the spell-caster's wand.
 * Seen/Mentioned: Used by Draco Malfoy while dueling Harry Potter in 1992.
 * Etymology: Latin serpens meaning "a snake" and Latin ortis meaning "source".

Silencio (Silencing Charm)

 * Pronunciation: sih-LEN-see-oh
 * Description: Makes something silent.
 * Seen/Mentioned: First used by Hermione in 1996 to silence a frog and a raven in Charms class, then later used to silence a Death Eater that was trying to tell his comrades where they were.
 * Etymology: Probably Latin silentium, "silence". Also, silencio and silêncio (which is closer to the English pronunciation) mean "silence" in Spanish and Portuguese, respectively.

Skurge

 * Pronunciation: SKUR-je
 * Description: Cleans up ectoplasm, the slime-like residue left by certain ghosts. The spell manifests as a blast of greenish suds.
 * Seen/Mentioned: The Harry Potter and the Chamber of Secrets video game. Harry finds it in a spell book in the Restricted Section of the Hogwarts Library(possibly misfiled) and uses it to clear doorways and treasure chests that have been slimed-over by malevolent ghosts.

Slugulus Eructo (Slug Vomiting Charm)

 * Description: A jet of green light strikes the victim, who then vomits slugs for ten minutes. The sizes of the vomited slugs decrease with time.
 * Seen/Mentioned: In Chamber of Secrets, Ron attempts to use it on Draco; the spell backfired and hit him instead. It is also a spell that can be bought in LEGO Harry Potter: Years 1-4.
 * Notes: In the film adaptation of Harry Potter and the Chamber of Secrets, an incantation was used, "Eat Slugs!", it's unknown if that's its true incantation or not, although it is unlikey to be.

(Sonorous Charm)

 * Description: This charm emits a magnified roar from the tip of the wand. This noise disrupts all in its path, and can even be used to harm opponents.
 * Seen/Mentioned: Harry Potter and the Prisoner of Azkaban (video game)

Sonorus

 * Pronunciation: soh-NOHR-uhs
 * Description: Magnifies the spell caster's voice when one's wand is pointing to the side of the caster's neck.
 * Seen/Mentioned: By Ludo Bagman in 1994 at the beginning of the Quidditch World Cup and by Albus Dumbledore several times in the Triwizard Championship. Used by Lord Voldemort several times during the Battle of Hogwarts in 1998.
 * Etymology: Latin sonorus, "loud; noisy".
 * Notes: The counter-spell is Quietus. In the film adaptation of Harry Potter and the Goblet of Fire Cornelius Fudge simply holds his wand to his throat while speaking, it is possible that he has performed a Nonverbal spell.

Specialis Revelio (Scarpin's Revelaspell)

 * Pronunciation: speh-see-AH-LIS reh-VEL-ee-oh
 * Description: Apparently causes an object to show its hidden secrets or magical properties.
 * Seen/Mentioned: Used by Hermione Granger to find out more of Harry's Advanced Potion-Making book in 1996. Used by Ernie Macmillan to find out ingredients of a potion. Its precise effects are unknown, as there are no recorded occasions of the spell being successful.
 * Etymology: Latin specialis, "particular;individual" and revelare (present tense revelo), "unveil".
 * Notes: In 1994, Severus Snape cast a similar spell, but with different words ("Reveal your secrets!"), on the Marauder's Map, though he may have just been saying those words as he cast the spell non-verbally. The spell may also be able to distinguish different ingredients in a potion, though this is noted to merely sound impressive.

Spongify (Softening Charm)

 * Pronunciation: spun-JIH-fy
 * Wand Motion:

http://images2.wikia.nocookie.net/__cb20110924150753/harrypotter/images/9/94/Softening-charm.png
 * Description: Softens the target
 * Seen/Mentioned: This charm is seen in The Standard Book of Spells, Grade 1 on Pottermore.

(Stealth Sensoring Spell)

 * Description: Detects those under magical disguise.
 * Seen/Mentioned: In 1996, Professor Umbridge cast this around her office.

Steleus

 * Pronunciation: STÉ-lee-us
 * Description: A hex that causes the victim to sneeze for a short period of time. This spell is used in duelling to distract the opponent.
 * Seen/Mentioned: It is only seen in Harry Potter and the Prisoner of Azkaban (video game).
 * Etymology: Steleus derives from the Latin sternuo, meaning I sneeze.

(Stinging Hex, Stinging Jinx)

 * Description: Produces a stinging sensation in the victim, resulting in angry red welts and occasionally the severe inflammation of the affected area.
 * Seen/Mentioned: Harry Potter inadvertently used one on Severus Snape during Occlumency lessons in 1996. It was non-debilitating in that instance, but it is stronger when intentionally cast, as shown by the results of Hermione Granger's Stinging Hex used on Harry Potter in 1998 to purposefully distort Harry's appearance. Lucius Malfoy calls it the Stinging Jinx in Harry Potter and the Deathly Hallows.

Stupefy (Stunning Spell)

 * Pronunciation: STOO-puh-fye
 * Description: Stuns victim. If used too forcefully, it will put the victim in an unconscious state.
 * Seen/Mentioned: Often; particularly by a number of wizards and witches (including Dolores Umbridge) against Minerva McGonagall in 1996. It's also taught by Harry in his D.A. meetings.
 * Etymology: English stupefy, which means 'to put into a stupor', a temporary vegetative state.
 * Notes: The physical manifestation of the spell is a beam of red light emanating from the caster's wand. The spell wears off after a short time, and can be countered by Rennervate. Nearly useless on magic-resistant creatures such as dragons, trolls and giants unless more than one Stupefy spell is used at the same time. The force of the spell is additive or perhaps even exponential, and it can cause severe injury if many spells are used on a target that is not normally resistant to its effects. Hagrid, as a half-giant, is impervious to this spell - or at least, a lone one.

(Supersensory Charm)

 * Description: Presumably causes the caster to have enhanced senses, or to be able to sense things they would not normally sense.
 * Seen/Mentioned: Mentioned by Ron outside of the Hogwarts Express in 2017 as a potential substitute for using mirrors while driving a Muggle auto mobile.

(Switching Spell)

 * Description: Causes two objects to be switched for one another
 * Seen/Mentioned: Harry contemplated using this spell against his dragon in the first task of the Triwizard Tournament. ((He considered swapping its fangs for wine gums)). Neville Longbottom misuses the spell, transplanting his ears onto a cactus.

(Taboo)

 * Description: A jinx which may be placed upon a word or a name, so that whenever that word is spoken, a magical disturbance is created which alerts the caster of the Taboo to the location of the speaker. Any protective enchantments in effect around the speaker are broken when the Tabooed word is spoken aloud.
 * Seen/Mentioned: In Deathly Hallows, this spell is placed on the word "Voldemort"; Harry, Ron and Hermione are tracked this way to Tottenham Court Road. Ron tells the other two to stop using the word as he began to fear the name might be a jinx, later discovering it to be a Taboo. Later in the book, Harry accidentally says Voldemort's name again, resulting in the trio being caught by Death Eaters and taken to Malfoy Manor.
 * Notes: A possible incantation could be "vomica vox" meaning "cursed word" presumably followed by the word.

Tarantallegra

 * Pronunciation: tuh-RAHN-tuh-LEHG-rah
 * Wand Motion:

http://images1.wikia.nocookie.net/__cb20120711182812/harrypotter/images/d/d9/Dancing-feet-spell.png
 * Description: Makes victim's legs dance uncontrollably (recalling the tarantella dance).
 * Seen/Mentioned: First used by Draco Malfoy on Harry in the Duelling Club in 1992.
 * Etymology: Italian tarantella, a kind of fast country dance once popular in parts of Italy, supposedly from the frantic motion caused by the bite of a tarantula; and allegro, a musical term meaning "quick".
 * Notes: It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.

Tentaclifors

 * Description: Transfigures the target's head into a tentacle.
 * Seen/Mentioned: LEGO Harry Potter: Years 5-7.

Tergeo

 * Pronunciation: TUR-jee-oh
 * Description: A spell used to siphon matter from a surface, eg. blood, ink, dust, etc.
 * Seen/Mentioned: Hermione Granger used the spell in 1996 to remove blood from Harry's face. It is later used to remove spilled ink from parchment. It was also used in 1997 to clean off a handkerchief by Ron and to dust off a picture of Gellert Grindelwald in Bathilda Bagshot's house by Harry Potter.
 * Etymology: Latin tergere, "wipe off; cleanse".

(Toenail Growth Hex)

 * Description: Causes the toenails to grow at an extreme and uncontrollable rate.
 * Seen/Mentioned: In 1996, Harry uses this to much applause from classmates.
 * Notes: This is a hex that is probably not approved by the Ministry of Magic, as it was invented by Severus Snape. And it is unknown whether "Toenail Growth Hex" is its real name, as its title was never mentioned.

(Tooth-growing spell)

 * Description: A spell that re-grows lost teeth.
 * Seen/Mentioned: Ted Tonks used it to re-grow Harry Potter's tooth that he had lost during the Battle of the Seven Potters.

(Transmogrifian Torture)

 * Description: Unknown effect upon victim; most likely extreme torture that can lead to death. Given the source, the Torture may not actually exist.
 * Seen/Mentioned: Gilderoy Lockhart suggested that it was this curse that "killed" Mrs. Norris after she was really found petrified on a torch bracket.
 * Etymology: English "transmogrify", meaning "to change or alter greatly, often to grotesque effect", possibly implying that the curse changes the shape of the victim to cause pain.

(Trip Jinx)

 * Description: A jinx to trip up or impede the target. Precise effects unknown.
 * Seen/Mentioned: Seen in 1996. It was cast successfully on Harry Potter by Draco Malfoy, when he and other members of the Inquisitorial Squad attempted to round up members of Dumbledore's Army.
 * Notes: In LEGO Harry Potter: Years 1-4, it can be bought at Wiseacre's Wizarding Equipment in Diagon Alley.

(Unbreakable Vow)

 * Description: Causes a vow taken by a witch or wizard to be inviolable; if they should break it, the consequence is death.
 * Seen/Mentioned: Snape takes an Unbreakable Vow with Narcissa Malfoy at the beginning of Half-Blood Prince, vowing to help Narcissa's son Draco with a task given to him by Voldemort, and to finish the task should Draco prove incapable. Fred and George attempted to force an Unbreakable Vow upon Ron as children. According to Ron, it causes death when the vow is broken.

(Unbreakable Charm)

 * Description: Makes something unbreakable.
 * Seen/Mentioned: Towards the end of Harry Potter and the Goblet of Fire, Hermione casts the charm on a jar, in which she puts Rita Skeeter in her Animagus beetle form to prevent her from transforming back into a human.

(Undetectable Extension Charm)

 * Description: Causes a container's capacity to be increased, without changing the object's appearance on the outside.
 * Seen/Mentioned: This spell is most likely the one Arthur Weasley used to allow eight people, six large trunks, two owls, and a rat to fit comfortably inside his modified Ford Anglia in 1992. Probably used on the tent in which the Weasleys, Harry and Hermione stay during the Quidditch World Cup in 1994; the tent is also used by Harry, Ron and Hermione as shelter in 1997. Also, Hermione cast this spell upon her handbag in the same year.

 * Description: A strong blast of wind is shot from the end of the wand, used to push objects out of the way.
 * Seen/Mentioned: Used in the video game version of Harry Potter and the Goblet of Fire.

Vera Verto

 * Pronunciation: vair-uh-VAIR-toh
 * Description: Turn animals to water goblets.
 * Seen/Mentioned: Used only once in the series, by Minerva McGonagall in the film version of Harry Potter and the Chamber of Secrets at her Transfiguration class.

 * Seen/Mentioned: Learned in first-year defence against the dark arts class.

Vipera Evanesca

 * Pronunciation: VIYP-er-uh ehv-uhn-EHS-kuh
 * Description: Counter Spell for Serpensortia. Seems not to merely "Vanish", but causes the snake to smoulder from head and tail until it is reduced to a pile of ashes.
 * Seen/Mentioned: Severus Snape cast this spell in 1992 at the Duelling Club to get rid of a snake that Draco Malfoy had conjured while duelling Harry Potter. Albus Dumbledore also may have used this spell to vanish Voldemort's snake during their Duel in the Ministry Atrium.
 * Etymology: Vipera is a genus of venomous vipers, a type of snake. Evanesca likely shares its origin with Evanesco, which means "disappear" in Latin.

Vulnera Sanentur

 * Description: Causes wounds and gashes to heal up and any blood to return to the victim.
 * Seen/Mentioned: Used by Severus Snape to heal the wounds of Draco Malfoy caused by the Sectumsempra curse cast by Harry Potter in the film adaptation of Harry Potter and the Half-Blood Prince.
 * Etymology: Vulnera Sanentur derives from the Latin vulnus, "wound," and sanare, "to heal"; it is translated "may the wounds be healed."

Waddiwasi

 * Pronunciation: wah-dee-WAH-see
 * Description: Appears to launch small objects through the air, though it was only ever used on a wad of chewing gum.
 * Seen/Mentioned: Used only once through the series, and that was by Professor Remus Lupin, who attacked a poltergeist with a wad of chewing gum, using this spell.
 * Etymology: There are many possibilities as to the etymology, least of all English wad, as in "a wad of gum".
 * Notes: This spell may be the Placement Charm, or else the Oppugno Jinx.

Wingardium Leviosa (Levitation Charm)

 * Pronunciation: win-GAR-dee-um lev-ee-OH-sa
 * Description: Levitates and moves the target; the wand motion is described as "swish and flick".
 * Seen/Mentioned: This spell is taught in early first-year charms classes; this came into good use later in that year, when Ron Weasley performed the spell to knock out a mountain troll; six years later, Harry uses the charm to levitate the side-car of his godfather's flying motorbike; Ron used it again this year to make a twig poke a tree.
 * Etymology: "Wingardium" almost certainly contains English wing, meaning "fly", and Latin arduus, meaning "high" . "Leviosa" probably originates from Latin levis, meaning "light".
