autumnus

autumnus

Latin

Alternative forms

• auctumnus, autumna

Etymology

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”).[1][2]
• From Proto-Indo-European *h₂sews- (“dry”), as in "drying up season."[3]

Possibly influenced by auctus (“enriched, enlarged, ample”).

• (Classical) IPA^(key): /au̯ˈtum.nus/, [äu̯ˈt̪ʊmnʊs̠]
