How Saussure is misinterpreted in Cognitive Grammar

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.
