Why is a sentence not complete without verb?

A sentence without a verb is not complete because verbs are the action words that tell us what is happening. They are the core of the sentence, providing the essential information about the subject's activity or state of being.

Here's a breakdown:

* Subject: The subject of a sentence is the person, place, or thing that the sentence is about.

* Verb: The verb tells us what the subject is doing or being.

* Object (optional): The object of a sentence is the person, place, or thing that is affected by the verb's action.

Without a verb, you only have a noun phrase or a subject. This simply states what is being discussed, but not what it is doing.

Example:

* "The cat" (incomplete) - This tells us *what* the sentence is about, but not what the cat is doing.

* "The cat sleeps" (complete) - This tells us *what* the sentence is about (the cat) and *what it is doing* (sleeping).

Think of it like this: A sentence is like a story. The subject is the main character, and the verb is the plot. Without a verb, you have a character standing still with no story to tell.
