What is the definition of a verb in sentence?

A verb in a sentence is the word or group of words that describes the action or state of being of the subject. It tells us what the subject is doing, what is happening to it, or what it is like.

Here's a breakdown:

* Action verbs: These verbs describe physical or mental actions.

* Examples: "She runs." "He thinks about it."

* State of being verbs: These verbs describe a condition, state, or existence.

* Examples: "He is happy." "The flowers are beautiful."

Key Points:

* Every sentence must have a verb.

* The verb is usually the most important word in a sentence.

* Verbs can be in different tenses (past, present, future).

Example:

* Subject: The dog

* Verb: barks

* Sentence: The dog barks.

In this sentence, the verb "barks" tells us what the dog (the subject) is doing.
