There are several types of grammar that help us understand how language works. The two main categories are descriptive grammar and prescriptive grammar. Descriptive grammar focuses on how language is actually used by speakers, capturing the rules and patterns that emerge naturally. In contrast, prescriptive grammar sets rules for how language should be used, often based on traditional standards. Another important type is generative grammar, which explores the underlying structures that allow people to create and understand sentences. Additionally, functional grammar emphasizes the role of language in communication, analyzing how context influences meaning. Each type offers valuable insights into the complexities of language.
