Step 1: Saussure's distinction
In Course in General Linguistics (1916), Ferdinand de Saussure, the father of structural linguistics, divided language study into two components:
- Langue: the structured system of language, the social and collective code shared by a community.
- Parole: individual speech acts, the personal use of langue in everyday communication.
Step 2: Eliminate distractors
(B) Metaphor and (C) Metonymy — these are figures of speech and rhetorical concepts, not Saussure's structural categories. ✘
Thus, Saussure's key differentiation of language is between langue and parole.
