When the same quality of two nouns is compared, adjectives change their forms in order to give degrees of comparison.
There are three degrees of comparison.
1. Positive degree
2. Comparative degree
3. Superlative degree
In the positive degree no comparison is made. The comparative degree is used to show a comparison between one thing and another while the superlative degree is used to show comparison between one thing and several others.
- To form the positive degree no inflection is required.
- To form the comparative degree an -er is added to the end of the adjective.
- To form the superlative degree an -est is added to the base adjective.
