Temporarily changes a transformed werewolf back into their human form (according to Gilderoy Lockhart)
- "Simple, yet effective — and another village will remember me forever as the hero who delivered them from the monthly terror of werewolf attacks."
- —Lockhart bragging about his supposed use of this spell to end a village's terror[src]
Since Lockhart is known for providing phony spells, that all of his books are known to contain a wealth of invented details, and given that there is no known cure for Lycanthropy, it is possible that this spell does not truly exist or that it has a different effect than Lockhart described (possibly just temporarily forcing a transformed person back into human shape, rather than preventing the change).
Homorphus is a combination of the Latin Homo meaning 'man' and the Greek morphe- meaning 'shape' or 'form'.
Behind the scenes
- Although this spell is described as a charm, its effects seem closer to Transfiguration.
- Considering the fact that there is no cure for lycantrophy, it is likely that this spell were a highly advanced piece of magic which returned the werewolf to its human state, only for him/her to turn into a werewolf by next full moon.
