Descriptive grammar (definition #1) refers to the structure of a language as it is actually used by speakers and writers. Prescriptive grammar (definition #2) refers to the structure of a language as certain people think it should be used.

Both kinds of grammar are concerned with rules--but in different ways. Specialists in descriptive grammar (called linguists) study the rules or patterns that underlie our use of words, phrases, clauses, and sentences. On the other hand, prescriptive grammarians (such as most editors and teachers) lay out rules about what they believe to be the “correct” or “incorrect” use of language。

Descriptive grammarians generally advise us not to be overly concerned with matters of correctness: language, they say, isn't good or bad; it simply is. As the history of the glamorous word grammar demonstrates, the English language is a living system of communication, a continually evolving affair. Within a generation or two, words and phrases come into fashion and fall out again. Over centuries, word endings and entire sentence structures can change or disappear.

Prescriptive grammarians prefer giving practical advice about using language: straightforward rules to help us avoid making errors. The rules may be over-simplified at times, but they are meant to keep us out of trouble--the kind of trouble that may distract or even confuse our readers.
