Pronunciation

  • Classical: [ˈɪ.tɪ.dẽː][1]
  • Ecclesiastical: [ˈiː.ti.dem][1]

Forms

itidem (not comparable)[1]

Etymology

It is from Latin ita (“so, thus”) + -dem, like īdem (“the same”).[2][1] De Vaan derives it from Proto-Italic *ita-dim; he connects ita with Proto-Italic *i-to- and compares Umbrian itek (“thus, as said”).[3]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus, where someone says he is to his father just what a good son should be.[3][4][2]

Semantic evolution

It is in the same way, just so, often answering ⟨ut⟩ or ⟨quasi⟩: in the Asinaria a lover is, like a fish, no good to a bawd unless fresh.[2] It also means likewise, also: Plautus has one cook and another flute-girl as well.[2] A Pompeian inscription uses it with a relative clause.[2] Church Latin glosses it in like manner.[5]

Timeline

  • c. 250–184 BC – Plautus, often with ut and quasi.[2][3][4]
