Pronunciation

  • IPA (Classical): [ɪn.tɛrˈwɛ.ni.oː][1]
  • IPA (Ecclesiastical): [in.terˈvɛː.ni.o][1]

Forms

interveniō (present infinitive intervenīre, perfect active intervēnī, supine interventum); fourth conjugation, impersonal in the passive[1]

Etymology

It is from inter- “between” and veniō “to come”.[2][1][3] De Vaan traces ⟨veniō⟩ to Proto-Indo-European *gʷm̥-yé- (“to come”), from Proto-Indo-European *gʷem- (“to step, come”).[4]

Earliest recorded meaning

The OLD's earliest citations are from Cato, of an interruption, and Plautus, of taking a hand in affairs.[2] Köbler dates Cato 234–149 BC.[5]

Semantic evolution

It meant to arrive while something is going on, as in Terence, to intervene in affairs, and of events to crop up, as in Plautus.[2] In Cato it meant to occur as a hindrance or interruption, and in Seneca to come into play and to lie between.[2] Lewis & Short give to come between, interrupt, intervene.[6]

It survives in Italian intervenire and Spanish intervenir, and English intervene (1580s) is a back-formation from intervention or from the Latin verb.[1][3]
