Forms

outono m (plural outonos)[1] Houaiss records the Latinising spellings auptuno, autono and optuno in the 15th century and oitono in 1836.[2] García de Diego lists atuno as old Portuguese, from Viterbo.[3] The etymological spelling outomno is found in a letter of 1795 and in a text of 1900.[4][5][1]

Etymology

It is inherited from Latin autumnus (“autumn”), written Old Galician-Portuguese outono in the oldest texts.[2][6][7][1]

The same Latin word is Galician outono, Spanish otoño, Occitan auton, French automne, Italian autunno and Romanian toamnă.[8][1] Corominas notes that besides Spanish it has lived on as a popular word only in Portuguese, Romansh and Romanian.[9] The French word, by contrast, was borrowed from Latin in the 13th century.[10]

The origin of the Latin word is unknown: Ernout and Meillet and others suppose it Etruscan, and de Vaan finds a foreign source conceivable, since no Proto-Indo-European word for autumn can be reconstructed.[11] Wiktionary adds proposals from *h₃ewǵ- (“cold”) and *h₂sews- (“dry”), the earlier Latin spelling auctumnus and a possible influence of auctus (“increased”).[1]

Earliest recorded meaning

Lorenzo's chronology has the word in a document of 1262: V dias d'outono and en tenpo d'outono “in autumn time”.[12] Houaiss and Cunha date it to the 13th century.[2][6]

Semantic evolution

Bluteau (1712–1728) describes it as the third season of the year, when the grapes are harvested and the latest fruits gathered.[13] Houaiss keeps “harvest time” as a sense of its own, and the DLP, Porto Editora and Michaelis record the crops of the season, outonos in the plural.[2][14][15][16]

The figurative “autumn of life”, the years before old age, is in Caldas Aulete's dictionary and in all the modern ones.[17][2] In Trás-os-Montes the word is used for the second growth of grass in a meadow after the main mowing.[18] Brazilian dictionaries define the season by the southern hemisphere, from the March equinox to the June solstice.[19]
