unità

Forms

unità f (invariable)^[1] Old forms are Old Italian unitate and Old Italian unitade.^[2][3]

Etymology

It is borrowed from Latin unitas (“oneness, unity”), from unus (“one”) with the suffix -tās.^{[4][5][6][1][7]} The GDLI calls it a learned word, and Körting notes that it is learned in every Romance language: Old Occitan unitat, French unité, Spanish unidad.^[8][9][4] It comes from the Latin accusative, with the ending cut short, as Sabatini–Coletti note; the older forms kept it as ⟨-tate⟩ and ⟨-tade⟩.^[10][2]

Earliest recorded meaning

DELI's first records are from the 14th century, as unitate in Jacopone, unitade in Dante and unità in the translation of Saint Augustine, for the quality of being one and indivisible.^[2] The translation of Augustine says that woman was made from man per commendare l'unitade (“to commend unity”).^[8]

Semantic evolution

Giovanni Villani, before 1348, already used the word for agreement and concord.^[2] The mathematical senses came in the 16th century: the units digit in Benedetto Varchi (before 1565) and the number one in Cosimo Bartoli (before 1572).^[2] Paolo Segneri used it in 1673 for the unity of God in three persons.^[2]

The Risorgimento made the political sense central: unità italiana is recorded in 1851.^[2] The dramatic unities of time, place and action of classical tragedy are recorded from 1875, and the unit of measure from 1891.^[2] In the 20th century the word came to mean a single element of a whole, partly under the influence of English unit, and in military use a body of troops or a single ship or aircraft (1905).^[11][2]
