Descriptive grammar is a branch of linguistics that seeks to describe the rules and patterns of a language as it is used by its speakers in real-life situations. There are several synonyms for descriptive grammar, including empirical linguistics, linguistic description, and grammatical analysis. These terms all refer to the systematic study of language as it is actually spoken and written, rather than to a prescriptive set of rules or standards. Descriptive grammar has become increasingly important in modern linguistics, as linguistic diversity and variation continue to grow across the world. Through descriptive grammar, we can gain a deeper understanding of language and the ways in which it is used to communicate meaning.
