Pronunciation

  • IPA (Ecclesiastical): [ˈprɛː.t͡ʃeps][1]

Forms

praeceps (genitive praecipitis); third-declension one-termination adjective[1]

Etymology

It is a possessive compound of prae “before” and caput “head”, with the combining form ⟨-ceps⟩, “having the head in front”.[2][1][3] Plautus and Ennius have the older ⟨praecipes⟩.[2][4]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, of plunging headlong and of impetuous behaviour, with the old form praecipes.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant head first, plunging headlong, as Cicero's throwing someone down praecipitem, of heavenly bodies setting, of constellations appearing upside down, and of age declining.[2][6] It meant rushing forward, of winds and storms violent, as in Virgil, and of persons precipitate, impetuous.[2] From Cato it meant of ground steep, sheer, and figuratively dangerous, as in Cicero, and in Sallust sudden, instant, abrupt.[2] As a neuter noun it meant a precipice, a sheer drop, as in Livy, and in praeceps headlong, in praecipitī on the brink of disaster.[2]

In Ecclesiastical Latin praeceps meant a precipice, steep place, cliff.[7] English precipitous came in the 1640s from obsolete French precipiteux.[8]
