What is a verb what verb?

It seems like you're asking about a "verb" and then using the word "what" in a way that doesn't make grammatical sense.

To help me understand what you mean, can you rephrase your question?

Here are some possibilities of what you might be asking:

* What is a verb? This would be asking for a definition of a verb.

* What verb should I use? This would be asking for a specific verb to use in a sentence.

* What is the verb in this sentence? This would be asking to identify the verb in a specific sentence.

Please clarify your question so I can give you a helpful answer!
