Etymology

Its origin is unknown, the OLD calling it doubtful and the TLL uncertain.[2][3][4] Wiktionary reports a derivation from Proto-Indo-European *h₃ewǵ- (“cold”) and a borrowing from Etruscan, comparing Etruscan 𐌀𐌕𐌖𐌍𐌄 (atune, “autumn”), and Etymonline suggests Etruscan too, comparing Vertumnus.[1][5] The older spelling ⟨auctumnus⟩ was perhaps influenced by auctus “increase”.[2][5] A neuter ⟨autumnum⟩ is also found.[2] Isidore derived it from the season when leaves fall and all things ripen.[6]

Earliest recorded meaning

The OLD's earliest citation is from Ennius, of autumn, and the TLL dates it from Ennius onwards.[2][3] Köbler dates Ennius 204–169 BC.[4]

Semantic evolution

It meant autumn, the third season of the year, as in Cicero and Caesar, and Tacitus' autumnō adultō “in late autumn”.[2][7] In Juvenal it stood for a year in counting, and in Ovid for autumn fruits, the harvest.[2] An adjective autumnus “autumnal” is found in Cato's imber autumnus “autumn rain”.[2][7]

In Ecclesiastical Latin it meant autumn.[8] British Medieval Latin also used it for the harvest and harvest work.[9] It survives in Italian autunno, French automne and Spanish otoño, and Old French gave English autumn in the late 14th century.[1][5]
