Pronunciation

  • /seˈmana/, [seˈma.na][1]

Forms

semana f (plural semanas)[1] Old Spanish wrote sedmana, setmana and sebmana beside semana.[2][3] The form sedmana is in the Fuero Juzgo of 1241 and is frequent in the 13th century.[2][3] The Leonese form selmana is in the Libro de Alexandre and in Juan Ruiz, and still reaches parts of Burgos.[2][4]

Etymology

It is inherited from Late Latin septimāna (“week”); Old Spanish semana has the same form beside older spellings.[2][5][6][7] The Late Latin noun is the feminine of the adjective septimānus (“of the seventh, of seven”), from septimus (“seventh”), from septem (“seven”).[8][9][1] The adjective, made with the suffix -ānus, was used of festivals falling on the seventh day of the month.[10][1] The numeral goes back to Proto-Indo-European *septḿ (“seven”).[11]

The same Late Latin word is Portuguese semana, Galician semana, Asturian selmana, Catalan setmana, Occitan setmana, French semaine, Italian settimana and Romanian săptămână.[12][4][1] Old Spanish also had forms with ⟨d⟩, ⟨t⟩ or ⟨l⟩ before the ⟨m⟩, and the Leonese one survives in dialects.[2][3]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, known from a 14th-century copy) counts time in weeks: „Allí yogo mio Cid complidas quinze semanas” “There my Cid lay a full fifteen weeks”.[13][5] In the poem tres semanas also means “a short time”.[14] The first text known in its own copy is the record of the Cortes of León of 1208, with a term of „tres semanas”.[13]

Semantic evolution

The word has always meant a series of seven days.[6][13] Alfonso X's prose counted it from Sunday to Saturday, and Moliner notes that Monday used to be seen as the second day, while it is now taken as the first.[15][16] Gómez de Silva notes that the seven-day week was introduced officially in the Roman Empire in the 4th century under Constantine, after Jewish and Babylonian use.[8]

Covarrubias explained the word as quasi septimana and recorded semanero, one who serves a week in an office.[17] The Autoridades added the sense of a period of seven months, years or centuries, as in las semanas de Daniel, and the entry Semana Santa, Holy Week.[18] The DLE also gives “a week's wages” and a form of hopscotch.[6] In Bolivia and Chile semana corrida is a full week's pay even with holidays in it.[6][19]
