It seems like you might be looking for a distinction between different aspects of grammar, such as:
* Prescriptive grammar: This focuses on rules and standards for "correct" language usage. It's often seen in textbooks and style guides.
* Descriptive grammar: This describes how language is actually used by people, regardless of whether it's considered "correct" or not. It's studied by linguists.
* Traditional grammar: This is a system of grammatical analysis based on Latin, often used in the past but less so now.
* Generative grammar: This is a theory of grammar that uses rules and principles to explain how language works.
If you can give me a bit more information about what you're interested in, I can help you understand the differences you're looking for!
