Pronunciation

  • /aˈun/, [aˈũn][1]

Etymology

It is inherited from Old Spanish ahú, inherited from Latin adhūc (“up to now; still”).[2][3][4][1] Old Spanish and Old Aragonese texts have adú (early 13th century, and a document of 1262) and the form above (a document of 1284); under the influence of adverbs and particles ending in ⟨-n⟩, such as bien, sin, non and según, it took its present form, as así became popular asín.[2][3][5] The reduced forms an and on are found above all in pastoral poets such as Juan del Encina and Torres Naharro.[2]

The Latin adverb was one of the few Latin words of more than one syllable stressed on the last.[2] It is a fusion of the phrase ad (“to”) hūc (“hither”), “up to here”.[1][6] Its classical sense was “until now”, but Livy and Lucan also used it of the past and the future, and authors of colloquial Latin such as Petronius used it with the modern Spanish sense.[2] Catalan àdhuc (“even”) is the same word taken over in a semi-learned form.[6][7]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, known from a 14th-century copy) has the word several times.[8][2] With the subjunctive it expresses a wish, as in Aún vea el día que de mí ayades algo “may I yet see the day when you have some reward from me”.[8][9] It also has the sense “even”: e aun demás los cuerpos e las almas “and even, besides, their bodies and souls”.[10]

Semantic evolution

The Auto de los Reyes Magos (c. 1180) has the temporal sense in Herod's words ¡Aún non só io morto! “I am not dead yet!”.[10] Alfonso X's prose uses it for “still, yet”, “nevertheless” and as an emphatic “even”.[11] The compound aunque “although” appears in Berceo; the Cid still writes aun and que apart.[2][8] Covarrubias gave Latin adhuc, etiam and nunc as its equivalents, and Autoridades the senses “still”, “also” and “nevertheless”.[12][13] Cuervo explained the temporal sense as “up to now”, carried over to a point in the past or the future.[14]

Usage notes

Aún and aun are one word, written with or without the accent according to the meaning.[4][1] With the accent it means “still, yet” and can be replaced by todavía, and it is usually pronounced in two syllables; without the accent it means “even”, like hasta, incluso or siquiera, and is pronounced as one syllable.[16][17][4] Wiktionary marks the use of either spelling in the other's sense as incorrect.[1] The phrase aun cuando means “even if, although”.[4]
