The fantasy of manners is a subgenre of fantasy literature that also partakes of the nature of a comedy of manners (though it is not necessarily humorous). Such works generally take place in an urban setting and within the confines of a fairly elaborate, and almost always hierarchical, social structure. The term was first used in print by science fiction critic Donald G. Keller in an article, The Manner of Fantasy, in the April 1991 issue of The New York Review of Science Fiction.
