Here's why:
* Missing subject: The sentence lacks a clear subject for the verb "correct." We need to know who or what is doing the correcting.
* Awkward phrasing: "We correct grammar" is an incomplete thought. It sounds like a statement about a general action, rather than a question about a specific instance.
Here are some ways to rephrase the question to make it grammatically correct:
* "Is the grammar in this question correct?" (This is the most straightforward way to ask the question.)
* "Are we correcting the grammar in this question?" (This clarifies that the question is about a specific action.)
* "Is the grammar in this question correct?" (This uses a more formal tone.)
