In one of the first reviews ever to be published of the CLG, Antoine Millet was critical of the form given to the text of the Course by its editors Bally and Sechehaye. In this article, I investigate Saussure’s writing style from the perspective of author philology. My research thus concerns itself with variations found in Saussure’s manuscripts for the Course of General Linguistics, starting from The Double Essence of Language and other examples from drafts of articles and preparatory notes for lectures. On one hand I highlight the importance of writing as a research instrument for Saussure, on the other hand I develop a hypothesis regarding the convergence of style and writing of his work. The upshot is to illustrate stylistic continuity in Saussure’s manuscripts. Finally, I seek to bring together stylistic variations in Saussure’s writing with notes made by Saussure in works dedicated to style and writing.
