How are nouns and pronouns different?

Nouns and pronouns are both words that represent people, places, things, or ideas. However, they differ in how they are used and what they refer to:

Nouns:

* Directly name a person, place, thing, or idea.

* Examples: *dog, table, happiness, London*

* Can be singular or plural.

* Examples: *cat, cats; book, books*

* Can be common or proper.

* Examples: *dog (common), Fido (proper); city (common), Paris (proper)*

Pronouns:

* Replace nouns to avoid repetition.

* Examples: *He, she, it, they, we, you, I*

* Refer to a noun that has already been mentioned (the antecedent).

* Example: *The dog barked. It was hungry.* (The pronoun "it" refers to the noun "dog")

* Can be personal, possessive, reflexive, relative, interrogative, demonstrative, or indefinite.

Here's a table summarizing the key differences:

| Feature | Nouns | Pronouns |

|---|---|---|

| Function | Directly name a person, place, thing, or idea | Replace nouns |

| Reference | Directly refer to the thing being named | Refer to a previously mentioned noun (antecedent) |

| Examples | Dog, table, happiness, London | He, she, it, they, we, you, I |

In short, nouns are the names of things, while pronouns are words that stand in for nouns.
