ABSTRACT
By functional phonology is normally meant the phonological theory predominantly Associated with the Russian, Nikolaj Sergeyevich Trubetzkoy (1890-1938). This theory is also known as Prague School phonology, and there exists a fair amount of literature on it. Much less has been written in English about the functionalphonological theory developed by the Frenchman André Martinet (1908-) and his associates. Both streams of functional phonology are founded on linguistic functionalism (see FUNCTIONALIST LINGUISTICS) and have much in common.
