Type: Charm
Pronunciation: pri-OR in-can-TAH-toh
Description: Forces a wand to show an "echo" of the last spell it performed.
Seen/Mentioned: Used by Amos Diggory in 1994 to discover the last spell cast by Harry's wand after it was found in the hands of Winky, a house-elf.
Etymology: Latin prior, "previous", and incantare, "to speak a spell" (past participle incantatum).
Notes: Can manifest in the form of the Reverse Spell effect, or Priori Incantatem, when wands with the same core attempt to do battle.
Notes (2): Apparently the spell is cumulative, with the user able to go further back and see spells that the wand performed after the latest spell. Harry suggests this in 1997. Hermione does not contradict his claim, suggesting this is true.
