Belles-lettres (French pronunciation: [bɛl lɛtʁ]) is a category of writing, originally meaning beautiful or fine writing. In the modern narrow sense, it is a label for literary works that do not fall into the major categories such as fiction, poetry, or drama. The phrase is sometimes used pejoratively for writing that focuses on the aesthetic qualities of language rather than its practical application. A writer of belles-lettres is a belletrist.
