The term ‘Sociolinguistics’, a branch of linguistics was first used in about 1965. Sociolinguistics is the study of language in relation to society or the study of the interaction between language and society.
Ferdinand de Saussure was influenced by Emile Durkheim in his studies. Emile Durkheim is a sociologist. He defined social facts as “things”. The application of these ideas to language study is obvious. Language can be considered as “a thing” separate from our use of it as individuals because it is inherited entire from the other speakers who teach it to us and it is not our product.
