Forms

dortoir m (plural dortoirs)[1] Old French dortor (13th century) and dortour, later dortouer (Joinville).[2][1]

Etymology

It is inherited from Old French dortour, inherited from Ecclesiastical Latin dormītōrium (“dormitory”), which already meant “bedroom” in imperial Latin; it was formed on dormītum, the supine of dormiō (“to sleep”).[3][4][1][5] Because the word first named the common bedrooms of monasteries, many Romance languages have forms remade on the Latin, such as Spanish dormitorio.[6] The same Latin word was later borrowed as dormitoire, a doublet.[1]

Cognate with Italian dormitorio and Occitan dormidor.[2]

Earliest recorded meaning

It is first found in Raoul de Cambrai (late 12th century), in the sense it had in Christian Latin, a common sleeping room.[3][4] Littré quotes the line in which a lady is hidden in the dortoir.[2]

Semantic evolution

The word kept its sense of a large room with many beds in a monastery, a school or a barracks.[4][7] About 1955 it took on a pejorative sense in apposition, a place whose people are at home only at night and work elsewhere, as in cité-dortoir, ville-dortoir and banlieue-dortoir.[4][7]

Timeline

  • late 12th century – First record in Raoul de Cambrai.[3]

  • 13th century – Joinville writes dortouer.[2]
  • c. 1955 – Cité-dortoir and ville-dortoir appear.[4][7]
