acerbo

Forms

acerbo (feminine acerba, masculine plural acerbi, feminine plural acerbe, superlative acerbissimo)^[1] Old Italian and the dialects also had Old Italian acervo, from the variant Late Latin acervus of Cisalpine Gaul and Italy.^[2][3]

Etymology

It is inherited from Latin acerbus (“harsh to the taste, sour; unripe”).^[4][5][6][1] DEI thought it possibly a learned word, but the LEI shows a wide popular development: Sardinian kervu, Friulian zerf (“colostrum”) and Lombard zerb, many of them from the variant acervus.^[7][2][8] The words French acerbe and Spanish acerbo are learned.^[5]

Latin acerbus belongs with Latin ācer (“sharp”) and the root of ago and acre.^[5][1] De Vaan derives it from a Proto-Italic form meaning “having sharpness” or “sharp”, from Proto-Indo-European *h₂eḱ- (“sharp”), with the same suffix as Latin adjectives in -idus;^[9][1] Wiktionary reconstructs Proto-Italic *akriðos.^[9][1]

Earliest recorded meaning

DELI's first record is in the 13th-century Cassino glosses, with the sense “not yet ripe, not fully grown”.^[4] The TLIO's first text is a poem of Bonagiunta Orbicciani of Lucca from the middle of the 13th century, and its first sense is “harsh, sour to the taste”.^[3]

Semantic evolution

By the end of the 13th century the word had the moral sense “harsh, cruel, painful”, which DELI dates to Guittone d'Arezzo;^[4][3][10] Dante writes of someone who seemed acerbo in bearing, and Old Italian applied it to sounds, judgments and rebukes.^[4][3][10]

From fruit the sense “unripe” passed to people and to life: età acerba is youth, and morte acerba a death that comes too early, an image already in Virgil's funere mersit acerbo.^[11][6] Today it also means “not yet fully formed or mature”, of a young person or an artist.^[12][13]
