Pronunciation

Forms

fosco (feminine fosca, masculine plural foschi, feminine plural fosche)[1] Old Italian also had fusco and fuscu.[2][3]

Etymology

It is inherited from Latin fuscus (“dark, dusky”), with the accusative fuscum.[4][5][6][1] The Latin word continues in most Romance languages, but not in Romanian or French: Dalmatian fosk (“black”), Sardinian fusku, Romansh fuosk, Occitan fosc, Catalan fosc, Spanish hosco and Portuguese fosco.[7][8][5] In the conservative Alpine dialects and in Dalmatian it has come to mean “black”.[8]

Latin fuscus goes back to Proto-Italic *fusko- and Proto-Indo-European *dʰus-ko- (“dark-coloured”).[9][1] It matches exactly the Old English ancestor of the English word dusk.[5][10][1] The suffix ⟨*-ko-⟩ also formed Latin adjectives for bodily features such as cascus and mancus, and de Vaan reports the view that the word first described a person's dark colouring.[9]

Earliest recorded meaning

The TLIO's first record is an anonymous poem from the Marche of the mid-13th century; its first sense is “dark, brownish or blackish and dull, without light”.[2] DELI dates the sense “dark-coloured” to Dante, before 1321.[4]

Semantic evolution

Dante writes Non frondi verdi, ma di color fosco (“not green leaves, but of a dark colour”), and speaks of the aura fosca, the murky air.[11][12] The figurative senses followed early: in Old Italian the word could mean morally clouded or stained, and as a noun “darkness”.[2] Petrarch, before 1374, used it for “sad”: I dì miei fur sì chiari, or son sì foschi (“my days were so bright, now they are so dark”).[4][11]

Later uses include dark weather, a grim look, and an uncertain or threatening future, and the phrase a fosche tinte “in dark colours”, for a gloomy description.[6][3][12] The noun foschia “haze”, a nautical word at first, is recorded from 1883.[4][13]
