Diachrony
The time dimension in the language is called diachrony. In the early twentieth century, the Swiss linguist Ferdinand de Saussure was the first who highlighted the difference between synchrony and diachrony. The diachronic approach shows how a language has changed over time. Most work in historical linguistics is diachronic in nature. A linguist can also be interested in constructing a purely synchronic description, without considering how the language had developed from an earlier form or what happened to it later [Trask, 49].
Diachronic is a term designating “change across time”. The term is in contrast to the “synchronic” which means “the same throughout time” or “without time”. A synchronic study of a language tries to set up the system as a functional whole, while a diachronic study considers language's historical evolution [2].
Diachrony (from the Greek "dia" – through and "chronos" – time) is the process of changing the system of linguistic items and their evolution in a time. Diachrony is understood quite unequivocal, as a historical way that each language item passes over as part of a language system, as well as a process of natural substitution of the previous structural state of linguistic item with a state that will follow [Jabborova, 1088].
