Here's a breakdown:
* Nouns are words that name people, places, things, or ideas. Examples: *dog*, *tree*, *love*, *city*.
* Pronouns are words that stand in for nouns. Examples: *he*, *she*, *it*, *they*, *we*.
* Verbs are words that describe actions or states of being. Examples: *run*, *jump*, *eat*, *sleep*, *is*, *are*.
So, while nouns, pronouns, and verbs all play important roles in language, they are distinct categories.
