Seen/Mentioned: Used by Dumbledore to save one of his students from a fall in 1993; Hermione Granger used it, to little effect, in 1998 to cushion an otherwise deadly fall.
Etymology: Likely the combination of the Anglo-French arester, meaning "to bring to a stop" and the Latin momentum, meaning "the force or strength gained whilst moving"; the literal translation hence is "Bring the force or strength gained whilst moving to a stop".

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 the three Unforgivable Curses.
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."

Pronunciation: AH-vi-fors
Description: Transforms the target into a bird

Seen/Mentioned: Although he was rather untrustworthy, it may not have occured at all, but Lockhart says he cured a Transylvanian farmer of this affliction.
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.
