Forms

costume m (plural costumi)[1] Old Italian forms include costuma, costumo, custume and constume.[2][3] Old Italian also had the plural costumora.[4]

Etymology

It is inherited from Vulgar Latin *costūmen (“custom”), a spoken-Latin form that replaced classical Latin cōnsuētūdō (“habit, custom”).[5][6][7][8][9] DELI, following Battisti, adds that the Italian form was very probably modelled on Old French costume and Old Occitan costum;[10][11][12][13] GRADIT gives Old French as the probable source, and Sabatini–Coletti think the word came through Provençal.[10][11][12][13] The TLIO likewise allows for French and Provençal influence.[2] The learned doublet is consuetudine, taken from the classical word.[1][14]

The shape of the Vulgar Latin form has long been debated.[14] Diez assumed an exchange of the suffix ⟨-ūdine⟩ for ⟨-ūme⟩;[14][9] Cornu and Havel proposed different chains of sound changes;[14][9] Gröber reconstructed a neuter and a feminine form side by side.[14][9] Devoto explains the ending as a cross with a form related to cōnstituō (“to set up”).[15]

The same word is French coutume, Occitan cosdumna, Catalan costum, Spanish costumbre, Portuguese costume, Logudorese costùmene, Friulian custùm and Engadine costüm.[16][5][9] The Latin noun is formed on cōnsuēscō (“to grow accustomed”), from con- and suēscō (“to become used to”).[5][1]

Earliest recorded meaning

The TLIO's first record is in the Venetian Proverbia que dicuntur, of the last quarter of the 12th century.[2] DELI's first record, from the Laude cortonesi of about 1260, has the sense “a person's habitual behaviour”.[10][17]

Semantic evolution

In Old Italian costume meant the habits of a person, of an animal and even of an object, the rules of good manners, moral conduct, the traditions of a people and customary law.[2] The sense “the customs and beliefs of a society in a given age” is in Brunetto Latini before 1294, and “moral conduct” in Bono Giamboni before 1292.[10] Petrarch writes that nature yields to habit, vinta dal costume.[4]

The sense “dress, manner of clothing” is first recorded in the TLIO and becomes common later: DELI dates it to 1812, and DEI has it from the 16th century and costume da bagno “swimsuit” from the 20th.[2][10][9] The word passed into French as costume, at first for customs and, from 1747 for dress, and French passed it on to English and German.[17][9] Today costume is also the theatre costume, and di costume describes writing about social habits, as in a romanzo di costume.[12][6]
