Wheréas the core of théoretical linguistics is concerned with studying languages at a particular point in time (usually the present), diachronic linguistics examines how language changes through time, sometimes over centuries. Historical linguistics enjoys both a rich history (the study of linguistics grew out of historical linguistics) and a strong théoretical foundation for the study of language change.

In American universities, the non-historic perspective seems to have the upper hand. Many introductory linguistics classes, for example, cover historical linguistics only cursorily. The shift in focus to a non-historic perspective started with Saussure and became predominant with Noam Chomsky.

Explicitly historical perspectives include historical-comparative linguistics and etymology.
