First attested

Ultimate origin
Proto-Indo-European (*ǵʰew-)

Pronunciation

  • Classical: [prɔˈfʊn.doː][1]
  • Ecclesiastical: [proˈfun.do][1]

Forms

profundō (present infinitive profundere, perfect active profūdī, supine profūsum); third conjugation[1] Catullus scans the first syllable long.[2]

Etymology

It is formed from prō- (“forth”) and fundō (“to pour”).[2][1] De Vaan derives ⟨fundō⟩ from Proto-Italic *χunde- and the present Proto-Indo-European *ǵʰu-n-d- (“to pour”), from the root *ǵʰew-, cognate with Ancient Greek χέω (khéō, “to pour”) and Sanskrit जुहोति (juhóti, “pours, sacrifices”).[3]

Earliest recorded meaning

Plautus is its first author,[4] whose miser in the Aulularia “weeps to pour away water when he washes”.[2]

Semantic evolution

It is to pour out a liquid, of springs to pour forth water, and to shed fluids from the body, especially blood;[2][5] animam or vītam profundere is to die or to give one's life, as Cicero's Miltiades who died in chains.[2][5] It is also to send out flames, to put forth shoots, and to pour out words or publish copiously, as in Lucilius and Cicero.[2]

Reflexively a crowd streams forth, as Caesar's archers, and feelings break out, as Cicero's pleasures that suddenly burst out after being held in.[2] It is to let the limbs hang loosely in sleep, as in Lucretius, and in the passive to prostrate oneself.[2][1] It also means to lavish or squander, as Cicero's “one must give, one must pour out money”.[2][5] Church Latin glosses it “pour out or forth, cause to flow, rush out”.[6]
