Pronunciation

  • Classical: [ɛjˈjʊs.mɔ.diː][1]
  • Ecclesiastical: [eˈjuz.mo.di][1]

Forms

eiusmodī (not comparable)[1] It is usually written separately, eius modī, and sometimes scanned as three syllables.[2] It is also spelled ejusmodī.[1]

Etymology

It is eius (“of this, of that”), the genitive of is (“he, that”), with modī, the genitive of modus (“measure, manner”), “of that manner”.[1][2][3] De Vaan derives ⟨is⟩ from Proto-Indo-European *(h₁)i- (“he, she, it”) and ⟨modus⟩ from Proto-Italic *medo- (“measure, judgement”) and Proto-Indo-European *med-o- (“measure”).[4]

Earliest recorded meaning

Köbler gives Terence as its first author,[3] who has “who has to deal with characters of that kind” in the Andria.[2]

Semantic evolution

It means of that kind or of such a kind, such, as Cicero's genus bellī est eius modī, “the nature of the war is such”, and also in such a manner.[2][1]

Church Latin glosses it “of this sort, of such kind”, with et eiusmodī, and the like.[5]

Timeline

  • 190–159 BC – Terence.[2][3]
  • 81–43 BC – Cicero of the nature of a war.[2][3]
