Pronunciation

  • /oˈtoɲo/, [oˈt̪o.ɲo][1]

Forms

otoño m (plural otoños)[1] Old Spanish wrote the word otonno, otono or otoño; learned spellings such as atupno, autumpno and attumpno also occur in medieval texts.[2][3] The Libro de Alexandre already has the Leonese form outunno, while another manuscript of the poem has the learned atu(m)pno.[4] An intermediate form autoño is recorded in 1537.[4]

Etymology

It is inherited from Old Spanish otonno, inherited from Latin autumnus (“autumn”).[4][5][6][1] The /w/ of the Latin diphthong /au/ kept the following /t/ from being voiced, as it did in auca (“goose”), which became oca.[1]

The word survived as a popular form only in Spanish, Portuguese, Romansh and Romanian, according to Corominas.[4] The same Latin word is Portuguese outono, Galician outono, Asturian otoñu, Romanian toamnă and Italian autunno, while Catalan autumne and French automne are learned forms.[7][8][9][10]

The origin of the Latin word is unclear: de Vaan notes that no Indo-European word for “autumn” can be reconstructed, so that the Etruscan origin proposed by others is conceivable.[11] Gómez de Silva also takes it, probably, from an Etruscan word for autumn.[12] Wiktionary compares such an Etruscan word and also lists derivations from Proto-Indo-European *h₃ewǵ- (“cold”) or *h₂sews- (“dry”).[1] Covarrubias and, still in the 19th century, Echegaray derived it from augeō (“to increase”), because autumn brings in the harvest.[13][14] Wiktionary allows that auctus (“enlarged, ample”) may have influenced the Latin form.[1]

Earliest recorded meaning

The earliest record in the CDH is the Fuero de Zorita de los Canes (1218–c. 1250), which taxes a foal otonnizo del otonno passado “born in the autumn just past”.[3] The sense is already the season between summer and winter, as in Alfonso X's Primera Partida, which places the third of the seasonal fasts de otonno after the feast of the Holy Cross.[3] Corominas's first record is the Primera Crónica General of about 1275.[4][5]

Semantic evolution

The word has been in use at all periods, although in some areas sanmiguelada “Michaelmas season” has replaced it.[4] Medieval texts counted it among the four seasons and linked it with the bodily humours: inuierno, verano, estio e otoño.[3] Covarrubias explained it in 1611 as the time of the grape harvest and of gathered fruit, and Autoridades (1737) defined it astronomically as the season that begins at the autumn equinox, when the sun enters Libra.[13][15]

The Academy's 1817 edition added the sense “second growth of grass or hay that the meadows give in autumn”, and the 1899 edition distinguished the astronomical season from the mild season of September to November in the northern hemisphere.[16][17] The same agricultural sense lives on in derivatives: Asturian otoñada and toñada name the grass that regrows after the summer mowing.[4] From such forms Corominas, following Carolina Michaëlis, derives retoñar “to sprout again” and retoño.[4][18] The figurative sense “time of life nearing old age”, as in el otoño de la vida, was noted by Román in Chile and is now in the DLE.[19][6]
