Pronunciation

Forms

détenu (feminine détenue, masculine plural détenus, feminine plural détenues)[1] As a noun: un détenu, feminine une détenue.[1][2]

Etymology

Used as an adjective, it is the past participle from French détenir.[3][4][5][2] The verb was borrowed in the 12th century from Latin dētineō (“to hold back, keep occupied”), from dē- and teneō (“to hold”), and was adapted to tenir.[4][3][1]

Earliest recorded meaning

The participle was used as an adjective from 1529, of a person held captive.[4][2]

Semantic evolution

The verb détenir meant “to seize” and then “to keep, retain”; it was used of keeping someone prisoner from 1306.[4][3][4][3] The participle followed this sense and was turned into a noun for anyone held in a place, especially a prisoner.[4][3] The Petit Robert dates the noun to the 18th century and the GLLF finds it in Voltaire, while the TLFi and the DHLF date it from 1826;[2][5][3][4][6] Quemada's datings record it about 1700.[2][5][3][4][6] Les jeunes détenus were minors held in a special institution, and by metonymy the institution itself.[3][7]

Timeline

  • 1306 – Joinville uses détenir for keeping someone prisoner.[3][4]
  • 1529 – The participle is used as an adjective.[4][2]
