Usage notes edit

  • The circumflex accent applied to the u in the past participle serves only to distinguish it from the prepositive du (of the). As such, the circumflex is omitted in the participle's other inflections: due f sg, dus m pl, dues f pl. The diacritic is likewise omitted in the derived adjective indu (undue, unwarranted) and its inflected forms, but retained in the adverbial derivative dûment and indûment, where it serves as an etymological marker signaling the elision of the letter e from the older spelling duement. These latter, however, may be rendered dument and indument according to the orthographic reforms advanced by the Conseil supérieur de la langue française and approved by the Académie française in 1990.
  • In negative constructions (e.g. ne pas devoir and ne plus devoir), the sense becomes "must not," "should not", etc.
    Je dois y aller.I must go. / I have to go.
    Je ne dois pas y aller.I must not go.
    Ne devriez-vous pas vous en aller ?Shouldn't you go away?
    Ça ne devrait plus vous poser de problèmes.
    That should no longer pose any problems.
