Adjectives and adverbs both are describing words. Adjectives describe a noun or a pronoun and are used to qualify them or used to describe the quality of them. However, adverbs are used to describe a verb. Both of these are modifiers. Modifiers are words that describe other words. For example:
- The quick boy jumped high.
- The Fox jumped quickly.
In the above example, the word quick is an adjective that describes the quality of the boy. Whereas in the second sentence, the word quickly is an adverb. Some people are of the view that adverbs always end with -ly. However, this is not always the case. Sometimes you may get confused between these two words but you should not worry. Just see how they function in a sentence. If they are describing the noun, they are adjectives otherwise adverbs.
