What is the difference between a noun and a pronoun?

Sure, here's the difference between a noun and a pronoun:

Noun:

• A noun is a person, place, thing, or idea that is named.
• Nouns can be singular (e.g., the book) or plural (e.g., the books).
• Nouns can be indefinite (e.g., the book on the table) or definite (e.g., the book I'm reading).

Pronoun:

• A pronoun is a word that takes the place of a noun.
• Pronouns can be singular (e.g., he, she, it) or plural (e.g., them).
• Pronouns can be definite (e.g., the book) or indefinite (e.g., the book I'm reading).

Here's an example that illustrates the difference between a noun and a pronoun:

• Noun: The book is on the table.
• Pronoun: He is the one who wrote the book.

Nouns are the things that are named, while pronouns are the words that replace those things.
