<u>For example,</u> this <em>cute</em> baby is eating an apple.
Whereas,<em> adverbs</em> refers to the set of words or word which qualifies the adjectives.
<u>For example,</u> the girls are speaking <em>softly</em>.
Hence, to form an adverb through adjective, they can be formed by adding –ly to the end of the word.
<u>For example,</u> they performed bad/badly in the exam
how did they perform? <em>badly</em>.
Hence, it is an adverb.
