Saya mau tau Description and prescription dari Linguistik. Jelaskan dalam bahasa sunda

Most work currently done under the name "linguistics" is purely descriptive; the linguists seek to clarify the nature of language without passing value judgments or trying to chart future language directions. Nonetheless, there are many professionals and amateurs who also prescribe rules of language, holding a particular standard out for all to follow.

Wheréas prescriptivists might want to stamp out what they perceive as "incorrect usage", descriptivists seek to find the root of such usage; they might describe it simply as "idiosyncratic", or they may discover a regularity that the prescriptivists don't like because it is perhaps too new or from a dialect they don't approve of.
