Distinguish between descriptive and prescriptive linguistics?

Descriptive linguistics is the scientific study of language as it is actually used by speakers and writers. It aims to describe and analyze the structure and use of language without making value judgments about what is considered correct or incorrect. Descriptive linguistics seeks to understand how language functions in different contexts and how it varies across different speakers and communities.

Prescriptive linguistics, on the other hand, involves prescribing rules and norms for how language should be used. It is concerned with establishing and enforcing standards of correctness and appropriateness in language usage. Prescriptive linguistics often involves creating style guides, grammar rules, and language norms that are considered to be "correct" or "proper" by a particular group or authority.

In summary, descriptive linguistics describes and analyzes language as it is used, while prescriptive linguistics prescribes rules and norms for how language should be used.
