Forms

costume m (plural costumes)[1] Houaiss records custume in 1262, costume in 1275, costome in 1296, and coustume and custue in the 15th century.[2]

Etymology

The word for a custom or habit is inherited from Vulgar Latin *consuetumen (“custom”), an alteration of Latin cōnsuētūdō (“custom, habit, usage”) in which the suffix was replaced, through a form like *costumine.[2][3][4] Houaiss calls the change of ending pan-Romance, and Corominas notes that it is shared by all the Romance languages and by every word in the suffix.[2][5] The oldest texts write Old Galician-Portuguese costume and Old Galician-Portuguese custume.[2][6]

The same Latin word is Galician costume, Spanish costumbre, Catalan costum, Occitan costum, Italian costume and French coutume.[5][1] The Latin noun had feminine gender, kept in Spanish and French, while Portuguese, Galician, Italian and Catalan made it masculine.[5][4]

The Latin noun is derived from cōnsuēscō (“to become accustomed”), itself from con- and suēscō (“to become used to”).[1]

Earliest recorded meaning

Houaiss's first record is custume in 1262, from Cunha's medieval index.[2] In the Cantigas de Santa Maria it already has the senses of today: com'é nosso costume “as is our custom”, ca atal é seu costume “for such is his habit”, aver por costume “to be in the habit of”.[6] The Galician Crónica Troiana tells of the feyturas et os custumes “the features and the customs” of those who besieged Troy.[6]

Semantic evolution

In medieval law the word meant a local rule established by usage; the records of the town council of Santiago use it for the customary law of the municipality.[6] Cardoso (1569) renders it with Latin mos, and Barbosa (1611) with mos and consuetudo.[7][8] Bluteau (1712–1728) defines it as something introduced and practised according to the habit of people or the usage of places.[9] Morais (1789) adds the plural for moral conduct, as in moço de bons costumes “a well-behaved young man”.[10] Old and legal senses include a tax regularly paid at the customs house and, in a witness's testimony, his ties of kinship or enmity with a party, hence às de costume “to the usual questions”.[2][11] In Brazil it is also an informal word for menstruation.[2][12]

Forms

costume m (plural costumes)[1]

Etymology

The word for a suit or outfit is borrowed from French costume.[2][12][4][15] The French word was itself taken from Italian costume (“custom”), used in painting for the manner of showing a figure's age, rank and period; it came to mean the way of dressing proper to a condition or period in 1747, and a person's set of clothes, as in a theatre costume, in 1777.[16] The Italian word goes back to the same Latin cōnsuētūdō as costume1.[2]

Semantic evolution

The original Caldas Aulete records the Brazilian senses “man's suit of trousers, jacket and sometimes waistcoat” and “woman's suit of jacket and skirt”.[15] Aurélio marks both as Brazilian.[12] Houaiss treats the theatrical sense as obsolete.[2]

Meanings

Noun

  1. (Brazil) A man's suit of trousers, jacket and sometimes waistcoat.[2][12][15]
  2. (Brazil) A woman's suit of jacket and skirt, usually of the same cloth.[2][12]
  3. Clothing suited to an occasion, especially to formal occasions: um costume de cerimónia.[2][12][1]
  4. (theatre, obsolete) A stage costume.[2][12]
