Pronouns are words that replace nouns. Examples include:
* He, she, it, they, we, you, I
Nouns are words that name people, places, things, or ideas.
While we don't use pronouns to refer to "school," there are some ways to avoid repeating the word "school":
* "The institution"
* "The place of learning"
* "My alma mater"
* "The building" (if referring to a specific school building)
