Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Proto-Indo-European (*h₂éwh₂os)

Pronunciation

  • Classical: [aˈwiː.tʊs][1]
  • Ecclesiastical: [aˈviː.tus][1]

Forms

avītus (feminine avīta, neuter avītum); first/second-declension adjective[1]

Etymology

It is formed from avus (“grandfather”) with the suffix -ītus.[2][1][3] De Vaan thinks it a recent formation modelled on marītus (“married, husband”);[3][1] Leumann explained it from the genitive ⟨avī⟩.[3][1] ⟨avus⟩ is Proto-Italic *awo-, from Proto-Indo-European *h2euh2- (“grandfather on the mother's side”), cognate with Hittite ḫuḫḫa- (“grandfather”), Gothic 𐌰𐍅𐍉 (awo, “grandmother”) and Old Irish aue (“grandson”).[3]

Earliest recorded meaning

De Vaan dates it from Cicero,[3] who has “would that he had attained his father's or his grandfather's glory!”.[2]

Semantic evolution

It means “of a grandfather, inherited from a grandfather”, as in Cicero's paternal and ancestral estates, and more widely “ancestral, of one's forefathers”, as Catullus' family heirlooms.[2][4]

Church Latin glosses it “ancestral, of a grandparent”.[5]

Timeline

  • 81–43 BC – Cicero of a grandfather's glory and estates.[2][4][6]
  • 81/79–52/50 BC – Catullus of family heirlooms.[2][6]

Meanings

Adjective

  1. Of a grandfather, inherited from a grandfather.[2][4][1][5]
  2. Ancestral, of one's forefathers.[2][1]

Usage notes

Avītus is also a Roman cognomen, as of Aulus Cluentius Avitus in Cicero.[2][4][1]
