Prescriptive lexicography is the practice of creating dictionaries that provide rules and guidelines for how words should be used in a language. It focuses on establishing standards for grammar, spelling, and usage, often reflecting the preferences of language authorities or experts. This approach aims to promote clarity and consistency in communication. In contrast to descriptive lexicography, which documents how language is actually used, prescriptive lexicography emphasizes what is considered "correct" or "proper." It often includes recommendations for word choice and style, helping users navigate the complexities of language and avoid common errors.
