Pronunciation

  • Classical: [ɔˈnʊs.tʊs][1]
  • Ecclesiastical: [oˈnus.tus][1]

Forms

onustus (feminine onusta, neuter onustum); first/second-declension adjective[1] Gellius cites honustus as an archaic spelling.[2][3]

Etymology

It is from Latin onus (“load, burden”) + -tus.[2][1] De Vaan explains it as a derivative in ⟨-to-⟩ of the s-stem, ⟨*onos-to-⟩.[4] He traces ⟨onus⟩ to Proto-Italic *ones- and Proto-Indo-European *h₃en-os (“load”), cognate with Sanskrit अनस् (ánas-, “heavy cart”); a link with Hittite anniya- (“to work”) is not compelling in meaning.[4] Wiktionary also allows that the formation is already Indo-European, comparing Ancient Greek ὀνοστός (onostós).[1]

Earliest recorded meaning

De Vaan and Köbler date it from Naevius.[4][5]

Semantic evolution

It means “loaded, laden”, of ships, carts and animals: Caesar's Bibulus hoped to meet laden ships but met empty ones.[2][3] With a genitive or ablative it is “laden with, full of”, as Cicero's ships loaded with grain, and it is used of trees heavy with fruit.[2][3] It also means heavily laden, as Horace's guest sent away loaded with gifts, and abundantly supplied, as Sallust's fertile land full of booty; and weighed down, as by armour or chains.[2]
