As the father of modern linguistics, Ferdinand de Saussure influences all aspects of linguistic development with no exception of Cognitive Grammar. A scrutiny of how Saussure is understood in Cognitive Grammar indicates that Saussurean linguistics is misinterpreted in terms of five core ideas: (1) langue, rather than parole, is given highest priority; (2) the internal relation of “signifier-signified” counts as the pairing of “form-meaning”; (3) “arbitrariness” is contradictory to “symbolicity”; (4) “arbitrariness” means “unmotivatedness”; (5) arbitrariness is not the inherent nature (...) of morphological and syntactic structures. This paper is intended to reassess these five ideas and argue that they depart further from Saussure’s thought. (shrink)
