Forms
iūdaeus (feminine iūdaea, neuter iūdaeum); first/second-declension adjective[1]
Etymology
It is borrowed from Ancient Greek Ἰουδαῖος (Ioudaîos),[1][2] from the name of Biblical Hebrew יְהוּדָה (Yehûdâ, “Judah”).[1][3] Georges and Köbler treat it as the adjective of Iūdaea (“Judaea”), from Ἰουδαία (Ioudaía).[4][5] Etymonline places an Aramaic form between the Greek word and the Hebrew name.[3]
Earliest recorded meaning
Köbler's first source for the noun is Cicero,[5] who uses the plural Iudaei, “the Jews”, in his speech for Flaccus.[6]
Semantic evolution
As an adjective it means “of Judaea, Jewish”;[5][7] Pliny the Elder uses it so,[5][7] and Columella calls a man Iudaeae gentis homo, “a man of the Jewish people”.[4] As a noun, masculine or feminine, it means a Jew or a Jewish woman.[8] Horace writes credat Iudaeus Apella, non ego (“let Apella the Jew believe it, not I”).[8]
In Christian and Medieval Latin it is the usual word for a Jew,[9][2] and through Anglo-French and Old French it gave English Jew.[3]
