A modifier that describes or limits a(n) noun or pronoun is an adjective.
Explanation:
An adjective is a word whose function is to modify a noun or a pronoun in a sentence. The adjective attributes a quality to the word it modifies. For instance, in the sentence "The rich man yelled at the poor boy," both "rich" and "poor" are adjectives and modify, respectively, the nouns "man" and "boy". In English, it is common to transform another type of word into an adjective by simply placing it before a noun or a pronoun. We can also create compound adjectives by connecting more than one word with a hyphen - "a ten-year-old girl".
