Ultimate origin

Pronunciation

  • Classical: [ɪŋˈnaː.wʊs][1]
  • Ecclesiastical: [iɲˈɲaː.vus][1]

Forms

ignāvus (feminine ignāva, neuter ignāvum, comparative ignāvior, superlative ignāvissimus); first/second-declension adjective[1]

Etymology

It is formed from in- (“not”) and gnāvus (“busy, active”).[2][1][3] De Vaan traces ⟨gnāvus⟩ to Proto-Italic *gnāwo- and Proto-Indo-European *ǵneh₃-uo- (“knowing”), from Proto-Indo-European *ǵneh₃- (“to know”), with the sense passing from “knowing” through “experienced” to “busy”; he compares Welsh go-gnaw (“active, persistent”).[3] Isidore of Seville explained it as “ignorant of the way”.[4]

Earliest recorded meaning

De Vaan gives Plautus as its first author.[3] In the Captivi a man hears that another was captured too: “so we weren't the only cowards”.[2]

Semantic evolution

It is lazy or slothful, as Varro's farmers who live in the villa and are lazier than those in the fields, and of conditions and conduct, as Plautus' slackest discipline.[2] It is sluggish, as Virgil's bees numb with hunger and cold, and of things torpid, as the dead water of Orcus.[2] It is faint-hearted or cowardly, ignoble (Plautus: homō ignāvissime), and of things useless, as Virgil's woods idle for many years.[2] Lewis and Short give iners and socors as synonyms and strēnuus, alacer and fortis as opposites.[5]

Church Latin glosses it “slothful, idle, listless, inactive”.[6]

  • 116–27 BC – Varro of lazy farmers.[2][7]
  • 70–19 BC – Virgil of sluggish bees and idle woods.[2][7]
