Diachronic Sociolinguistics: History of the Term and the Branch of Linguistics
The subject of the suggested research is a new sub-branch of sociolinguistics – diachronic sociolinguistics: its sources, subject of research, objectives and terminological definition. Analysis of the linguistic thought has showed the formation of this separate branch of socio-linguistics during a centennial period, beginning with some concepts in the classic papers of Jan Baudouin de Courtenay, then Ferdinand de Saussure and such remarkable representatives of the French Sociolinguistic School as Antoine Meillet and Joseph Vendryes.
