What is the difference between a pronoun and a proper noun?
A pronoun is a word that takes the place of a noun. Pronouns can be subjects of the sentence (I, he, she, it, you, we, they) or express possession (his, her, your, my, mine, yours, its, our, their, ours, theirs).
Proper nouns are specific, capitalized nouns. Like all nouns, they are either people, places, objects, activities, or ideas.
Examples of proper nouns:
New York City
Muslim (can be a proper adjective as well)
