Pronunciation

  • Classical: [eːˈniː.tɔr][1]
  • Ecclesiastical: [eˈniː.tor][1]

Forms

ēnītor (present infinitive ēnītī, perfect active ēnīsus sum or ēnīxus sum); third conjugation, deponent[1] The perfect participle is usually ēnīxus in the sense “give birth” and ēnīsus in the other senses.[2][3] Sallust uses ēnīsum est as an impersonal passive.[2]

Etymology

It is from Latin ex- (“out”) + nītor (“to lean, strive”).[2][4][1] De Vaan lists it among the derivatives of nītor, which he reconstructs as Proto-Italic *kniχw-et- and connects with cōnīveō (“to be tightly closed”).[5]

Earliest recorded meaning

Plautus has it first, in the Pseudolus, of someone who soils his cloak while clambering to his feet.[2][5][6]

Semantic evolution

It is to force one's way out or up, to climb, and also to struggle over mountains, as Tacitus has troops crossing the Pyrenees and the Alps.[2][3] Terence uses it of taking pains for someone, and this sense of striving, often with ut or an infinitive, is common in prose.[2][3] With a mother as subject it means to give birth: Varro writes of a pregnant woman who does not go far from her work and brings back the child she has borne there.[2] De Vaan glosses it “to struggle out, give birth”.[5]

Timeline

  • c. 250–184 BC – Plautus of struggling to one's feet.[2][6]
  • 190–159 BC – Terence of striving on someone's behalf.[2][6]
  • 116–27 BC – Varro of giving birth.[2][6]
