Revulsion Jinx

"...I forced him to let go with a Revulsion Jinx..."

- Hermione explaining her use of the spell on Yaxley.

The Revulsion Jinx (Relashio) is a spell that forces an object or person to release its hold on something, or repels objects with the force of another object.

Possible Use

 * Mundungus Fletcher may have used this spell in 1996 outside the Three Broomsticks, when Harry, angered by Mundungus's plundering of Sirius Black's possessions, grabbed the former by the throat.
 * Remus Lupin may have used this spell against Harry Potter in 1997 after Harry accused him of cowardice for deciding to abandon his family.

Behind the scenes

 * In Harry Potter and the Goblet of Fire, Harry Potter used it underwater against the Grindylows during the Second Task of the Triwizard Tournament. The spell produced a flash along with a jet of boiling water in this setting.
 * In the film version of Harry Potter and the Order of the Phoenix, Dolores Umbridge is seen using a spell to force a kissing couple away from each other. The spell used may have been a non-verbal form of the Revulsion Jinx.
 * In the film version Harry Potter and the Deathly Hallows: Part 2, it was Hermione Granger who used this jinx to free the dragon guarding the high-security vaults in Gringotts Banks during the 1998 Break-in of Gringotts Wizarding Bank.

Etymology
Probably from the French verb relâcher meaning "to release, to set free", or Italian rilascio (pronounced the same way as the spell) meaning "I release".
