Origins

From earlier auctumnus, of unclear ultimate origin: * From Proto-Indo-European *h₃ewǵ- (“cold”) (compare Old Irish úacht, Lithuanian áušti (“to cool off”), Old Armenian ոյծ (oyc)). * Borrowed from an Etruscan word, like Etruscan 𐌀𐌕𐌖𐌍𐌄 (atune, “autumn”). * From Proto-Indo-European *h₂sews- (“dry”), as in "drying up season." Possibly influenced by auctus (“enriched, enlarged, ample”).
