Most descriptive adjectives can show degree of quality or quantity by forming two degrees of comparison: the comparative degree and the superlative degree. These degrees are formed from the positive degree, which is the usual form of adjectives. The comparative and superlative forms can be simple (bigger, biggest) or compound (more attentive, most attentive).
The comparative degree and the superlative degree are formed by adding the suffixes ER and EST to the positive form of the adjective or by using MORE and MOST before the positive form of the adjective. The choice of ER, EST or MORE, MOST depends on the mostly number of syllables in the adjective.
