Ultimate origin

Pronunciation

  • Classical: [juːˈda.ɪ.kʊs][1]
  • Ecclesiastical: [juˈdaː.i.kus][1]

Forms

iūdaicus (feminine iūdaica, neuter iūdaicum); first/second-declension adjective[1]

Etymology

It is borrowed from Ancient Greek Ἰουδαϊκός (Ioudaïkós),[2][3][4] the adjective of Ἰουδαῖος (Ioudaîos, “Jew”),[4] which goes back to the name of Biblical Hebrew יְהוּדָה (Yehûdâ, “Judah”).[1] Köbler and Georges place it among the derivatives of Iūdaea (“Judaea”).[5][6]

Earliest recorded meaning

Its first use is in Cicero's speech for Flaccus, where he speaks of the ill will roused by the “Jewish gold”.[7][8][5]

Semantic evolution

In Classical Latin it means “relating to the Jews” and “of or from Judaea”: Tacitus uses it of troops stationed in Judaea and calls unleavened bread panis Iudaicus,[3][8] and Scribonius Largus prescribes bitumen of Judaea.[7] Isidore of Seville describes a Iudaicus lapis, a white stone shaped like an acorn.[9]

Christian and Medieval Latin used it widely of the Jewish people and their law;[5][2] Bede speaks of the Iudaica gens.[2] English borrowed Judaic in the 1610s, from French and directly from Latin.[4]
