Prescriptive grammar is a set of rules and guidelines that dictate how a language should be used. It focuses on establishing standards for correct usage, often based on traditional norms. This approach aims to promote clarity and consistency in communication, helping speakers and writers avoid common errors. Unlike descriptive grammar, which observes how language is actually used in everyday life, prescriptive grammar emphasizes ideal forms. It often includes rules about sentence structure, punctuation, and word choice, guiding individuals to adhere to established conventions in their writing and speech.
