"The raven continued to open and close its sharp beak, but no sound came out."

The Silencing Charm (Silencio) is a charm that renders the victim temporarily mute.[1] Working on both beasts and beings, it is immensely difficult to perform, more so on ravens than frogs.[1] If performed incorrectly, the target will swell up to an immense size and begin making deafening sounds.[1]


Professor Filius Flitwick had his fifth year Charms students practise this spell at Hogwarts School of Witchcraft and Wizardry, and assigned it as homework to those who could not perform it competently in class.[1]

Harry Potter July, 1993 Harry loses his Temper with Marjorie Dursley and unintentionally casts a silencing charm both non-verbally and wandlessly, either or both of these factors cause the already difficult spell to fail, so it instead causes her to swell until she resembles a balloon and also causes her to float to the roof.
Fifth years 1995 Fifth-years work on this spell in Charms using bullfrogs and ravens.
Hermione Granger 18 June, 1996 Hermione cast this spell on a Death Eater during the Battle of the Department of Mysteries, which caused the spell he used to attack her to be a lot less damaging. He still knocked her out, though, and did "enough damage to be going on with," according to Pomfrey.
Lord Voldemort 2 May, 1998 He used this spell on the defenders of Hogwarts during the final battle.
Lyall Lupin Unknown He used the spell to silence his Werewolf Son, Remus Lupin, during his monthly transformations in order to protect his son for any unwanted attentions from their neighbours or the ministry when Remus was a child.[3]
