Confidence
Established
Formation
Derivation
First attested
204–169 BC, Ennius
Ultimate origin
Proto-Indo-European (*h₁rep-)

Pronunciation

  • Classical: [ˈra.paːks][1]
  • Ecclesiastical: [ˈraː.paks][1]

Forms

rapāx (genitive rapācis, comparative rapācior, superlative rapācissimus, adverb rapāciter); third-declension one-termination adjective[1]

Etymology

It is formed from rapiō (“to snatch, seize”) with the suffix -āx.[2][3] De Vaan traces ⟨rapiō⟩ to Proto-Italic *rap-i- (“to seize”) and Proto-Indo-European *h1rp-i- (“to seize”), cognate with Ancient Greek ἐρέπτομαι (eréptomai, “to devour”) and Albanian rjep (“to tear off, rob”).[3]

Earliest recorded meaning

Ennius has the sweeping wave,[2] and Plautus' Menaechmi “quarrelsome, grasping, fraudulent men”.[2][3]

Semantic evolution

It means “given to seizing”, of beasts of prey and of Catullus' Scylla, and as a noun a predator; of rivers and other forces it is “sweeping away”.[2] Of people it is “greedy, rapacious”, as in Plautus, and without blame of nature, which Cicero says seeks out nothing so greedily as its like.[2][4] Rapax was also the title of a legion in Tacitus.[2]

Church Latin glosses it “ravening, rapacious, greedy”, and as a noun “extortioner”.[5]
