belles-lettres

belles-lettres, n. pl.
  (ˌbɛl ˈlɛtr)
  Also 8 -letters, belle-lettre.
  [Fr.; lit. ‘fine letters, i.e. literary studies,’ parallel to beaux arts the ‘fine arts’; embracing, according to Littré, grammar, rhetoric, and poetry.]
  Elegant or polite literature or literary studies. A vaguely-used term, formerly taken sometimes in the wide sense of ‘the humanities,’ literæ humaniores; sometimes in the exact sense in which we now use ‘literature’; in the latter use it has come down to the present time, but it is now generally applied (when used at all) to the lighter branches of literature or the æsthetics of literary study.
