Forms
avus m (genitive avī); second declension[1] Inscriptions have avs and the older nominative avos.[2][3]
Etymology
It is inherited from Proto-Italic *awo-, inherited from Proto-Indo-European *h₂éwh₂os (“grandfather, maternal uncle”).[4][1][5] Cognate with Hittite ḫuḫḫa- (“grandfather”), Armenian հաւ (haw, “grandfather”), Gothic 𐌰𐍅𐍉 (awō, “grandmother”) and Old Irish aue (“grandson”).[4][3][2]
Earliest recorded meaning
De Vaan dates it from Plautus,[4] who has ibi meī maiōrēs sunt sitī, pater, avos, proavos, abavos, “there my forefathers lie buried, father, grandfather, great-grandfather, great-great-grandfather”.[3][5]
Semantic evolution
Avus is “a grandfather” (Cicero of Gaius Gracchus: clārissimō patre, avō, maiōribus, “of a most famous father, grandfather and ancestors”), and in poetry “an ancestor, forefather” (Virgil: Mantua, dīves avīs, “Mantua, rich in ancestors”).[3][2][1] Wiktionary also records “an old man”.[1]
Church Latin glosses it “grandfather”.[6] Köbler records it widely in early medieval law codes.[5]
