Forms

aceto m (plural aceti)[1] Old forms include Old Italian axeo, Old Italian aseo, Old Italian axedo, Old Italian asedo and Old Italian axè in the north, and Old Italian acito and Old Italian achitu in the south.[2][3]

Etymology

It is inherited from Latin acētum (“vinegar”).[4][5][3][1] The Latin noun is the neuter of an adjective *acētus belonging to aceō (“to be sour”) and acēscō (“to turn sour”), formed like exolētus beside exolēscō.[6][1][7] The DÉRom reconstructs a masculine Proto-Romance noun;[8] Latin texts have the masculine only in the Latin Oribasius, while the neuter is usual from Plautus on.[8]

The word survives in every Romance language except Romanian and modern French: Dalmatian akáyt, Sardinian agedu, Friulian asêt, Engadine aschaid, Old French azet and Occitan azet, and Spanish acedo and Portuguese azedo as adjectives meaning “sour”.[9][5][10] Through a form with the consonants transposed it reached the Germanic languages (German Essig), and Slavic took it either from Balkan Latin or from Gothic, passing it to Romanian oțet.[9][10]

The Latin verb goes back to Proto-Indo-European *h₂eḱ-, with a stative suffix, “to be sharp”.[11] DELI and Nocentini also trace the word to this root meaning sharp or pungent, the root of ago “needle”.[4][5]

Earliest recorded meaning

The TLIO's first record is the Lombard poem of Pietro da Bescapè (1274), in the form axeo, for vinegar, the sour product of fermented wine.[2][9] Nocentini and Devoto–Oli date the word to 1274;[5][12][4] DELI's first record is Dante's Commedia (1313–19).[5][12][4]

Semantic evolution

Old Italian aceto was made from wine and also from apples, pears and sorbs;[2] aceto squillitico was vinegar steeped with squill.[2] Figuratively it already meant spite or ill will, and a proverb said that from a bad payer one gets either vinegar or sour wine.[2] Boccaccio recalls the vinegar and gall given to Christ on the cross, and an old proverb says Adamo mangiò el fico e noi bevemo l’aceto (Adam ate the fig and we drink the vinegar).[13]

From Benedetto Varchi (before 1565) the word also meant biting wit, a sense Treccani connects with Horace's “Italian vinegar”.[4][14] In some Lombard and Adriatic dialects the word became feminine when the article was misdivided, and Ligurian forms replaced the ending with that of past participles.[9]

Chemistry built a large family on the word from the late 18th century: acetato and acetico (1791) are from French words coined by Guyton de Morveau in 1787, acetone (1846) from French, acetilene (1875) from English.[4][5] Modern cooking terms include aceto balsamico, the aged vinegar of Modena and Reggio Emilia, and sott’aceto (pickled), from which sottaceto (1846).[14][5]
