---------- Degree of Adjectives----------------
Adjectives have three forms called degrees of comparison - the positive , the comparative and the superlative.
- The positive is the simple form of the adjective without expressing increase or decrease of the original quality. An adjective is in the positive form when it does not express comparison.
Example : Darian is a tall boy.
- The comparative form of the adjective expresses a comparison between two or between one and a number taken collectively.
Example : Darian is taller than Abraham.
- The superlative is that form which expresses a comparison between one and a number of individuals taken separately.
Example : Darian is the tallest of all.
