Which linguist is credited with developing the concepts of Competence and Performance in the study of language?

Explanation

The concepts of Competence and Performance were introduced by Noam Chomsky to distinguish between a speaker's internal knowledge of language (competence) and the actual use of language in real situations (performance). Other linguists like Charles Sanders Peirce, Ferdinand de Saussure, and Edward Sapir contributed to linguistics but did not formulate these specific terms.
