Latin in Harry Potter

The Harry Potter series of books is one I have read through once or twice, and only recently have I discovered the Latin hidden throughout the book. The Latin can best by looking to the many spells in the book, most influenced by Latin. A good example would be the spell Crucio, a spell used to torture an opponent. The word comes from Latin, meaning literally, "I torture." Crucio isn't the only spell though, as a more complex example would be priori incantatem, a spell used to reverse the effects of other spells. The words come from Latin a priori, from the earlier, and incatare, sing or recite in reference to a spell. For someone fluent in Latin, Harry Potter becomes a much more interesting book.
