Is pronoun a substitute to noun?

Yes, that's a great way to think about it! Pronouns are essentially substitutes for nouns. They stand in for nouns to avoid repetition and make writing more concise and natural.

Here's a simple example:

* Original: "The cat sat on the mat. The cat was very fluffy."

* With pronoun: "The cat sat on the mat. It was very fluffy."

In the second sentence, "it" replaces "the cat," making the sentence smoother and more concise.

Here's a breakdown of how pronouns function:

* They refer to a noun that has already been mentioned: This is called the antecedent.

* They take the place of the noun: This means the pronoun has the same grammatical function as the noun it replaces.
