Pronouns:
* Replace nouns: They stand in for nouns to avoid repetition.
* Examples: he, she, it, they, we, you, I, this, that, these, those.
* Refer to specific people, places, or things: but they don't give a specific name.
Proper Nouns:
* Name specific people, places, or things: They are always capitalized.
* Examples: John, Paris, Amazon River, Earth, Thanksgiving.
* Don't replace nouns: They are the specific names themselves.
In a nutshell:
* Pronouns are like stand-ins, replacing nouns.
* Proper nouns are the actual names of things.
Here's an example:
Sentence: John went to the store and bought a book. He read it on the bus ride home.
* Pronoun: "He" replaces the proper noun "John".
* Proper Noun: "John" is a specific person's name.
