Final answer:
A comparative adjective is used to show comparison between two or more nouns or pronouns by highlighting their qualities.
Step-by-step explanation:
A comparative adjective is used to show comparison between two or more nouns or pronouns. It is used when we want to compare the qualities of two or more things.
