The Prague School was an influential linguistic circle established in 1926 in Prague that made several important contributions to structuralist linguistics. It emphasized language as a system of functionally related units and studied it synchronically. The Prague School developed the concept of distinctive features in phonology and the notion of markedness. It also distinguished between the theme and rheme in sentences, with the theme being given information and the rheme being new information. The general approach of the Prague School can be described as a combination of functionalism and structuralism.
