Literature (from Latin litterae (plural); letter) is the art of written work and can, in some circumstances, refer exclusively to published sources. The word literature literally means "things made from letters" and the pars pro toto term "letters" is sometimes used to signify "literature," as in the figures of speech "arts and letters" and "man of letters."Literature is commonly classified as having two major forms—fiction and non-fiction—and two major techniques—poetry and prose.
Literature may consist of texts based on factual information (journalistic or non-fiction), as well as on original imagination, such as polemical works as well as autobiography, and reflective essays as well as belles-lettres.
Literature can be classified according to historical periods, genres, and political influences. The concept of genre, which earlier was limited, has broadened over the centuries. A genre consists of artistic works which fall within a certain central theme, and examples of genre include romance, mystery, crime, fantasy, erotica, and adventure, among others. Important historical periods in English literature include Old English, Middle English, the Renaissance, the 17th Century Shakespearean and Elizabethan times, the 18th Century Restoration, 19th Century Victorian, and 20th Century Modernism. Important intellectual movements that have influenced the study of literature include feminism, post-colonialism, psychoanalysis, post-structuralism, post-modernism, romanticism, and Marxism.
