Pronunciation

  • Classical: [ˈkrɛ.poː][1]
  • Ecclesiastical: [ˈkrɛː.po][1]

Forms

crepō (present infinitive crepāre, perfect active crepuī); first conjugation, no passive, no supine stem[1]

Etymology

It is inherited from Proto-Italic *krepa-, from Proto-Indo-European *ḱrep- (“to rattle, crackle”).[2] The OLD calls it onomatopoeic.[3] Cognate with Hittite karpi- (“anger”) and Sanskrit कृपते (kṛ́pate, “groans”).[2][3] De Vaan suggests the vowel of the present may come from the perfect ⟨crepuī⟩, and that Varro's ⟨percrepis⟩ may be a remnant of a third-conjugation verb.[2]

Earliest recorded meaning

De Vaan dates it from Plautus,[2] whose miser in the Aulularia asks “what rattled like iron just now?”[3]

Semantic evolution

It is to make a sharp noise, to rattle, clatter, creak or crackle: of doors opening in Plautus and Terence, of burning herbs in Propertius, and in Cato and Martial of breaking wind.[3] Seneca uses it of a house that collapsed with a crash.[3] Transitively it is to make something rattle;[3] Horace and later writers use it of rattling out words, of talking on and on about something.[3] Lewis & Short note that it is mostly poetic or post-Augustan, classical prose preferring concrepō.[4]

Church Latin glosses it “crack, burst asunder, resound”.[5]
