Errors in the Use of Adjectives and Adverbs
The first step in identifying modifiers is to read the sentence and look for descriptive words. You should then look at each descriptive word and try to determine whether it is an adjective or an adverb.
An adjective describes a noun or pronoun and answers the questions: how many, which one, what kind?
She is a good tennis player. (What kind of tennis player is she?)
This is an easy exercise. (What kind of exercise is it?)
An adverb describes a verb, an adjective or another adverb and answers the questions: when, where, how, why, and to what extent?
She plays tennis well. (How does she play?)
This exercise is relatively easy. (To what extent is it easy?)
An easy way to identify adverbs and to distinguish them from adjectives is to look at the ending. Most adverbs are formed by adding -ly to the adjective: He worked quickly.
