Forms

semana f (plural semanas)[1] Houaiss records the medieval spellings sumana (13th century) and semana (14th century), and somana in 1561.[2] García de Diego lists somana as Old Portuguese and Galician, and Wiktionary gives somana as an alternative form.[3][1]

Etymology

It is inherited from Late Latin septimāna (“week”), written Old Galician-Portuguese sumana and Old Galician-Portuguese semana in the medieval texts.[2][1][4] The Late Latin noun is the feminine of the adjective septimānus (“of the number seven”), used as a noun; the adjective is formed from septimus (“seventh”), the ordinal of septem (“seven”).[2][1] In classical Latin the adjective was said of the nones that fell on the seventh day of the month.[5][2]

The same Latin word is Galician semana, Spanish semana, Catalan setmana, Occitan setmana, French semaine, Italian settimana and Romanian săptămână.[6][1] The older Spanish form was Old Spanish setmana, and Asturian selmana is found in Leonese too.[3][1]

Nascentes notes the Latin noun in the Theodosian Code and in the pilgrimage account of Egeria.[7] He adds that Cornu and Nunes, because the /n/ between vowels was kept, took the word for a semi-learned or foreign one.[7]

Earliest recorded meaning

Houaiss dates the word with forms of 1188–1230 and 1209 taken from Machado, and quotes sumana in the 13th century.[2] A text of 1224 still writes the Latin septimana.[7] The Historia Troiana has o primeyro dia da semana “the first day of the week”.[8] The sense was the period of seven days from the start.[2][8]

Semantic evolution

Cardoso's dictionary of 1569 translates the word with Latin hebdomas, and Morais in 1813 defines it as the seven days into which the month is divided.[9][10] Morais also records estar de semana, to be on duty for a week in a rota.[10] Vieira adds Semana Santa, the last week of Lent, and the week's wages.[11] By metonymy the word came to mean the work done in the week and the pay for it, and also the working days as opposed to Sunday.[2][12] A modern sense is the span of days in which an event is held, as in the Semana de Arte Moderna of São Paulo.[12][2]

The word passed into the Portuguese-based creoles: Kabuverdianu sumána, Kristang sumana and Guinea-Bissau Creole sumana.[1] It was also borrowed by Konkani and by Amerindian languages of Brazil such as Mbya Guarani.[1]

Timeline

  • 1188–1230 – setmanas, the first form in Houaiss, from Machado's records.[2]
  • 1224 – the Latin septimana in a text of the Leges.[7]
  • 13th century – sumana.[2]
  • 14th century – semana; the Historia Troiana has o primeyro dia da semana.[2][8]

  • 1712–1728 – Bluteau reports Venegas's derivation from Latin septem mane “seven mornings”.[14]

Usage notes

Semana Santa is Holy Week, from Palm Sunday to Easter Sunday;[2][12] semana furada is a week with one or more holidays, and semana inglesa a working week that ends on Saturday at midday or earlier.[2][12] The saying na semana dos nove dias “in the week of nine days” means never.[17][11]

Bluteau, after Venegas, derived the word from Latin septem mane “seven mornings”; the modern dictionaries derive it from the Late Latin septimana.[14][2]
