Note: There are three ways to pronounce Latin: the ancient Roman pronunciation (not accurately reconstructed until the early 1900's), the Italian-like pronunciation used by the Catholic Church, and the English-like pronunciation still used by lawyers. For example, Caesar is pronounced KAI-sahr in the Roman system, CHAY-sahr in the Church, and SEE-zer in the English system.

The pronunciations given here are in the English system, except for a few words that occur mainly in Church Latin. Be prepared to hear wide variation in the ways all of these words are pronounced.
