Forms
aetās f (genitive aetātis); third declension[1]
Etymology
It is a contraction of aevitās, from Latin aevum (“age, lifetime”) + -tās.[2][3] Wiktionary traces it to Proto-Italic *aiwotāts, from *aiwom and the suffix *-tāts.[1] The full form aevitās survives in the Twelve Tables, Varro and Cicero's laws, and inscriptions spell it ⟨etas⟩.[2]
Earliest recorded meaning
The Twelve Tables have aevitās in the rule “if illness or old age is a hindrance”.[2] Köbler dates the Twelve Tables to about 450 BC.[4]
Semantic evolution
It was the number of years one has lived, one's age, and the age of things such as wine or words.[2] It also named a period of life (infancy, youth, old age), an age group, youth or old age in particular, and the whole of one's lifetime, aetātem meant “all one's life”.[2] By extension it was human life in general and a historical age or era.[2][1]
Isidore distinguished the age of a man, divided into infancy, youth and old age, from the ages of the world.[5] In medieval British Latin it was a person's age, childhood, old age and an age group.[6] It survives in Italian età, Spanish edad and Portuguese idade, and Old French aage gave English age.[1]
