Literary theory is the systematic study of the nature of literature and of the methods for literary analysis. Since the 19th century, literary scholarship includes literary theory and considerations of intellectual history, moral philosophy, social philosophy, and interdisciplinary themes relevant to how people interpret meaning. In the humanities in modern academia, the latter style of literary scholarship is an offshoot of post-structuralism. Consequently, the word theory became an umbrella term for scholarly approaches to reading texts, some of which are informed by strands of semiotics, cultural studies, philosophy of language, and continental philosophy.
