Pronunciation

  • Classical: [ˈan.nu.ʊs][1]
  • Ecclesiastical: [ˈan.nu.us][1]

Forms

annuus (feminine annua, neuter annuum); first/second-declension adjective[1]

Etymology

It is formed from annus (“year”) with the suffix -uus.[2][1] De Vaan derives ⟨annus⟩ from Proto-Italic *atno- (“year”) and Proto-Indo-European *h₂et-no- (“a going, year”), from a root meaning “to go, wander”, so that the year was “what goes round”.[3] Cognate with Oscan akeneí (“in the year”) and Umbrian acnu (“year”).[3]

Earliest recorded meaning

Köbler gives Naevius as its first author,[4] and de Vaan dates it from Plautus,[3] whose pimp in the Pseudolus says he must be given a year's provisions that day.[2]

Semantic evolution

It is of the year or yearly, as Accius' “in the yearly course”, and of what is paid, offered or recurs every year, as Cicero's “yearly changes of cold and heat”.[2] Of magistrates and commands it is appointed for a single year, as Cicero's state bound by annual magistrates, Caesar and Nepos;[2][5] it is also what lasts a year, as in the Rhetorica ad Herennium, where “a year's talk would hardly be enough”, and a year's supply.[2][5]

Church Latin glosses it “yearly, annual, of a year's duration”.[6] Köbler finds it in Aldhelm, the Bible, capitularies, councils and charters.[4]
