Here's a breakdown:
* Noun: A word that names a person, place, thing, or idea (e.g., dog, house, happiness).
* Pronoun: A word that replaces a noun (e.g., he, she, it, they).
Adjectives tell us:
* What kind: *red* car, *delicious* food, *heavy* box
* How many: *five* books, *several* friends, *no* time
* Which one: *that* house, *this* book, *the* dog
* Whose: *her* car, *my* book, *the teacher's* desk
Essentially, adjectives help us paint a clearer picture of the noun or pronoun they modify by adding details and making our language more descriptive.
