Course in General Linguistics was created in 1916.

"Course in General Linguistics" is a seminal work by Swiss linguist Ferdinand de Saussure that laid the foundation for modern structural linguistics. It introduces key concepts such as the distinction between langue (language system) and parole (individual speech), synchrony and diachrony, and the arbitrariness of linguistic signs. Saussure's ideas have had a lasting influence on the field of linguistics and semiotics.

Ferdinand de Saussure is considered the father of modern linguistics because of his groundbreaking work in structural linguistics, particularly in his book "Course in General Linguistics." He introduced key concepts such as the signifier and signified, language as a system of differences, and the distinction between synchronic and diachronic linguistics, which had a profound impact on the field of linguistics. His ideas laid the foundation for structuralism and semiotics in the study of language and communication.

No, you would not capitalize "grammar," "phonetics," and "linguistics" unless they are part of the official title of a specific course or program, such as: "Introduction to Grammar."
