Borrowed from Latin autumnus (“autumn, fall”), of uncertain etymology. First attested in 1306, replacing several inherited forms (cf. proto-Italian octummio, attested in a Latin document from 762, via Late Latin autumnius). The Latin etymon is directly continued by Romanian toamnă, Aromanian toamnã (unless these reflect the variant in a-), Italian autono (Northern Italy, 15th c.), Romansch utuon (Engadine), Spanish otoño (→ Logudorese Sardinian atónzu, Campidanese atógniu), Portuguese outono, and via Vulgar Latin *atumnus by Friulian atum (“october”), Romansch atun (Sursilvan), aton (Surmiran). Provençal autoun (“autumn harvest”) could be Latin-influenced; French autonne is likely, and Catalan autumne certain to be a borrowing from Latin.
