Synchronic linguistics In the 20th century several linguistic movements operated. They were historicism, structuralism, functionalism, generativism and others. Lets mention at least the most important ones. The following extracts have been taken from BUSSMANN, H.: Routledge Dictionary of Language and Linguistics. Routledge 2004 Structuralism: It builds its theories on the idea that „the language is a set of signs“. The signs are then organized in structures. Functionalism: It is based on the idea that the form in any language follows the function not vice versa. Generativism: It studies the human ability to create (generate) sentences and understand them.
