The purpose of this paper is to analyze the concept of linguistic change by providing numerous examples. There is also an attempt to show and reveal how this concept appeared and was interpreted by different linguists. The author will also discuss its causes, peculiarities and distinguishing features. Eugen Coseriu places himself at the top of the researchers with his work Sinchrony, Diachrony and History. The problems of linguistics change. The basic assumption is that language changes cannot be explained on the level of the langue. Coseriu refers to Humboldt, Hegel and Aristotle, adopting from Humboldt the distinction between energeia and ergon, which goes back to Aristotle, and from Hegel the view of man as a historical being by means of language. Language changes basically depend on the description of speech and the facts presented by the the speakers’ activity.
