Arthur Weasley used this spell in Diagon Alley in 1992 to repair Harry Potter's spectacles after Harry broke them when tumbling out of the Floo Network connected to the fireplace in Borgin and Burkes respectively.
The word reparo is the first person singular form of the first conjugation verb (-are) reparare, meaning "to renew" or "to revive" in Latin. The word oculus is the nominative singular form of the word meaning "eye". Thus, the spell Oculus Reparo roughly means "I renew the eye". Unfortunately, from a grammatical point of view, this statement is incorrect, because although it follows the common SOV word order, the word oculus is in the nominative singular case, when it should be accusative singular, as it is the object of the sentence.
Behind the scenes
- In the film adaptation of Harry Potter and the Philosopher's Stone, Hermione Granger uses this spell on Harry Potter's glasses during their first ride on the Hogwarts Express. This does not happen in the scene in the book, making it non-canon.
- The use of this charm by Arthur Weasley has not been confirmed, as it may have been the general fixing spell.
- Hermione Granger uses this in Diagon Alley despite being underage and hence not permitted to use magic outside of school but is in a controlled magical place.
- In LEGO Harry Potter: Years 1-4, Ron tries to use this spell to fix Harry's glasses but instead turns a wizard's hat into a frog.
- Although in the book, Mr Weasley taps Harry's glasses when using this spell, in the second film Hermione moves her wand in a similar manner to the "swish and flick" used for the Levitation Charm; this is seen often throughout the first two films.
