Literature consists of written productions, often restricted to those deemed to have artistic or intellectual value. Its Latin root literatura/litteratura (derived itself from littera, letter or handwriting) was used to refer to all written accounts, but intertwined with the roman concept of cultura: learning or cultivation. Literature often uses language differently than ordinary language (see literariness). Literature can be classified according to whether it is fiction or non-fiction and whether it is poetry or prose; it can be further distinguished according to major forms such as the novel, short story or drama; and works are often categorised according to historical periods or their adherence to certain aesthetic features or expectations (genre).
