Pronunciation

  • Classical: [rɛ.pɛnˈtiː.nʊs][1]
  • Ecclesiastical: [re.penˈtiː.nus][1]

Forms

repentīnus (feminine repentīna, neuter repentīnum); first/second-declension adjective[1]

Etymology

It is formed from Latin repēns (“sudden”) + -īnus.[2][1] The origin of repēns is uncertain.[3] De Vaan prefers to connect it with rapiō (“to seize”), as an aorist participle Proto-Indo-European *h₁rep-n̥t- (“seizing”);[3] Walde–Hofmann and Pokorny derived it from a root ⟨*wrep-⟩ “to twist”, “with a sudden turn”, and Ernout–Meillet from re- and the root of pendō.[3]

Earliest recorded meaning

Terence, Andria: my heart is moved by the wonder of so great and so sudden a blessing (tam repentīnō hōc bonō).[2][4]

Semantic evolution

It means sudden, happening without warning, as Cicero's adventus hostium repentīnus, “a sudden enemy attack”, as opposed to an expected one, and of an enemy acting without warning (Livy).[2][5] Dē repentīnō is “all of a sudden” (Apuleius).[2] It is also said of what appears without previous development, as Cicero's ignōtī hominēs et repentīnī, “unknown upstarts”, of an extempore speaker, and of things made in an emergency, as Varro's makeshift huts.[2]

Church Latin glosses it “sudden”.[6]
