Ferdinand de Saussure seated in a formal pose, wearing a dark suit with a vest and sporting a thick mustache, circa 1900. — Linguistics Much of the foundation of 20th-century sociolinguistics was created by the Swiss linguist Ferdinand de Saussure (1857–1913).

Ferdinand de Saussure fundamentally transformed the study of language by establishing it as a structured social phenomenon, a shift that launched 20th-century structural linguistics.1

His influence is primarily defined by his distinction between two core concepts:

Langue: The underlying system of conventions and rules that makes speech understandable within a society.12
Parole: The actual, individual utterances or speech acts performed by a person.12

By separating these, Saussure allowed linguists to analyze language as a formal system (synchronically) independent of its historical evolution (diachronically). Furthermore, he treated language as a sign-system, identifying the sign as consisting of a "signifier" (the sound or mark) and a "signified" (the concept). These methodologies provided the foundation for semiotics and structuralism, influencing fields ranging from anthropology to psychoanalysis. His lectures, compiled in the Course in General Linguistics, remain a cornerstone of modern linguistic science.12
