Confidence
Established
Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Proto-Indo-European (*Hrewp-)

Pronunciation

  • Classical: [prae̯ˈrʊp.tʊs][1]
  • Ecclesiastical: [preˈrup.tus][1]

Forms

praeruptus (feminine praerupta, neuter praeruptum, superlative praeruptissimus); first/second-declension adjective[1]

Etymology

It is the past participle of praerumpō (“to break off in front”), used as an adjective.[2][1][3] De Vaan traces ⟨rumpō⟩ to Proto-Italic *ru-n-p- (“to break”), a nasal present of Proto-Indo-European *Hreup- (“to break”), cognate with Sanskrit रोपयति (ropáyati, “causes racking pain”) and Old English rēofan (“to break, tear”).[4]

Earliest recorded meaning

Köbler's first source is Catullus;[3] the OLD's earliest example is Cicero's Verrines, of headlands and sheer rocks.[2]

Semantic evolution

Its literal sense is “broken off into a sheer drop, precipitous, steep”, of rocks, cliffs and slopes.[2][1] Seneca uses it of speech broken off short, as in the half-articulated words of angry men.[2] Figuratively it describes a situation on the edge of disaster, as Velleius' “sheer and doubtful danger” to the state, and of persons “headstrong, hasty”, as Tacitus' young noble of headstrong temper.[2][1]

Timeline

  • 81–43 BC – Cicero of sheer rocks.[2][3]
  • 81/79–52/50 BC – Catullus.[3]
  • c. 20 BC–30 AD – Velleius of a critical danger.[2][3]
  • 98–115 AD – Tacitus of a headstrong youth.[2][3]
