Adjectives change in form when they show comparison. These changed forms are called Degree of Comparison. Adjectives have three degrees of comparison which are as follows:
Positive Degree: An adjective is said to be in a positive degree when there is no comparison.
Comparative Degree: An adjective is said to be in a comparative degree when there is a comparison between two nouns/pronouns.
Superlative Degree: An adjective is said to be in a superlative degree when there is a comparison between more than two nouns/pronouns.
