In linguistics and grammar, a pronoun (abbreviated PRO) is a word that substitutes for a noun or noun phrase. It is a particular case of a pro-form.
A noun is a word for a person, a place, or a thing. A pronoun is a word that takes the place of a noun in a sentence. A noun or a pronoun functions as the subject of a sentence or a clause, and as the object of a verb or a preposition. Noun as subject of the sentence: Aunt Jane made cookies for Jack and Jill.
