What is the name of word that describes verb in a sentence?

There isn't a single word that describes a verb in a sentence. Instead, we use different terms depending on the specific aspect of the verb we want to describe. Here are some examples:

* Verb: This is the most general term, simply indicating that the word is a verb.

* Finite Verb: This describes a verb that is conjugated to show tense, person, and number.

* Main Verb: This is the primary verb in a sentence, the one that carries the main action.

* Auxiliary Verb: These verbs help form verb phrases, like "be," "have," or "do."

* Transitive Verb: A verb that requires a direct object.

* Intransitive Verb: A verb that doesn't require a direct object.

* Regular Verb: A verb that forms its past tense and past participle by adding "-ed".

* Irregular Verb: A verb that does not form its past tense and past participle by adding "-ed".

So, depending on the specific detail you want to describe about the verb, you can use different terms.
