Azymes is an archaic English word for the Jewish matzah, derived from the Greek word αζυμος ("unleavened") for unfermented cakes in Biblical times; the more accepted term in modern English is simply unleavened bread or matzah, but cognates of the Greek term are still used in many Romance languages (French pain azyme, Italian azzime). The term does not appear frequently in modern Bible translations, but was the usual word for unleavened bread in the early Catholic English Douay-Rheims Bible.

Azymite was a term of abuse used by Greek rite Christians against Latin Rite Christians.
