What is a Subject in Grammar?

In grammar, the subject of a sentence is the person, place, thing, or idea that performs the action or is described in the sentence. It tells us who or what the sentence is about.

Key Points about the Subject:

• The subject usually comes before the verb in a sentence.
• It can be a noun (a person, place, or thing), a pronoun (he, she, it, they), or even a phrase acting as a noun.
• The subject agrees with the verb in number (singular or plural).

Examples:

• She runs every morning.
  ("She" is the subject doing the action "runs".)

• The dog barked loudly.
  ("The dog" is the subject performing the action "barked".)

• Reading books is fun.
  ("Reading books" is a phrase acting as the subject.)

Why is the Subject Important?

The subject is essential because it helps us understand who or what the sentence is about, making the sentence clear and meaningful. If you want, I can also explain more about subjects, like different types or how to identify them!
