Here's why:
* Noun: A noun is a word that names a person, place, thing, or idea. "Shoe" names a type of footwear.
* Adjective: An adjective describes a noun. For example, "red shoe" uses the adjective "red" to describe the noun "shoe."
* Adverb: An adverb modifies a verb, adjective, or another adverb. For example, "He walked quickly" uses the adverb "quickly" to modify the verb "walked."
