* Formal Grammar: This is a broad term encompassing any approach to grammar that focuses on formal rules and structures. Generative grammar is a type of formal grammar.
* Transformational Grammar: This term specifically refers to Noam Chomsky's early model of generative grammar, which emphasized transformations between different sentence structures. While it's not as widely used today, it is still sometimes used synonymously with generative grammar.
* Principles and Parameters Theory: This is a later development of generative grammar that focuses on universal principles of language structure, with variation accounted for by specific parameters set for each language.
* Computational Linguistics: This field often draws upon generative grammar principles for developing language models and computational analyses of language.
It's important to note that while these terms have some overlap with generative grammar, they are not always interchangeable. Depending on the context, you might need to clarify what specific aspect of generative grammar you're referring to.
