Avada Kedavra (Killing Curse)
Pronunciation: /əˈvɑːdə kəˈdɑːvrə/ ə-vah-də kə-dah-vrə
Description: Causes instant, painless death to whomever the curse hits. There is no countercurse or method of blocking this spell; however, if someone sacrifices their life for someone else, the person who was saved will not encounter any adverse effects of any curses by the specific attacker (e.g. when Lily Potter sacrificed her life for Harry Potter at Voldemort’s hands, Harry became immune to curses cast by Voldemort). One of the three Unforgivable Curses.
Survivors: Only two people in the history of the magical world are known to have survived the killing curse – Harry Potter and Voldemort; the latter was only saved by his horcruxes. Harry was hit twice directly. Phoenixes can also survive a killing curse. They burst into flame as they would do in old age and are reborn from the ashes. This occurred in Harry Potter and the Order of the Phoenix.
Seen/mentioned: First said (not by name) at the beginning of the first book when Harry arrives at the Dursleys’ home. Seen first in Goblet of Fire against Muggle Frank Bryce, and in every book following.
Suggested etymology: During an audience interview at the Edinburgh Book Festival (15 April 2004) 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 it 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.”[5] Rowling’s use of this name may have been influenced by Latin cadaver = “corpse”.
