The first step we are going to take is to know the etymological origin of the word diachrony that now concerns us. In this case, we can state that it is a term that derives from Greek, as it is the result of the union of several components of that language:
-The prefix "dia-", which can be translated as "through".
-The noun “kronos”, which is synonymous with “time”.
-The suffix "-ia", which is used to indicate "quality".
The concept refers to the succession of events along the weather .
Often the diachrony is linked to the analysis of social phenomena according to their different historical phases . In this way the acts in its chronological continuity.
Starting from that meaning, we can establish, therefore, that the different eras of humanity are a clear example of diachrony. Thus, the Middle Ages are followed by the Middle Ages and this is the Modern Age, for example.
You can differentiate between diachrony and synchrony . While the diachronic is related to a development in a temporal sequence, the synchronic refers to the observation of phenomena at the specific moment of their evolution. In other words: diachrony refers to considering the same event at different times, while synchrony is associated with different events at the same time.
A diachronic perspective of the Argentine history For example, you can start your tour at the beginning of the XIX century with the fight for independence , continue with the internal conflicts between unitary and federal, review the process of constitutional organization, analyze the alternation between military and democratic governments, study the last military dictatorship that developed between 1976 and 1983 and reach the democratic stage that is still in force and in development.
The different temporal approaches also appear in the field of linguistics . Diachrony, in this area, involves studying the historical evolution of the language, considering the changes it experienced from its emergence to the present. Synchrony, on the other hand, focuses on a precise moment of language development.
In the linguistic field we can emphasize that a fundamental figure in the study of the Language as well as in the establishment of the terms diachrony and synchrony is the Swiss academic Ferdinand de Saussure (1857 - 1913), who is considered the father of the study of the language modern He talked about these concepts in his work "General Linguistics Course".
The works, ideas and principles of that one served for many other scholars, among which was the British linguist John Lyons (1932), a reference within the field of semantics, which took another step. Thus, he came to establish, among other things, that it was really complicated to establish a clear and precise differentiation between what was the synchronous change of the language and the diachronic change of it.
