Prescriptive linguistics is an approach to language that focuses on establishing rules and norms for correct usage. It aims to guide speakers and writers on how to use language properly, often emphasizing grammar, punctuation, and style. This approach is commonly found in educational settings, where teachers instruct students on standard language conventions. Unlike descriptive linguistics, which observes and analyzes how language is actually used in various contexts, prescriptive linguistics advocates for specific standards. It often references authoritative sources, such as grammar books and style guides, to support its recommendations, ensuring clarity and consistency in communication.
