Degrees of Comparison

English adjectives and adverbs commonly distinguish three degrees: the positive (the basic form), the comparative (expressing a higher degree than is present in something else) and the superlative (expressing a maximal degree).

Comparative and superlative adjectives: formation

The comparative is formed with -er or more; the superlative is formed with -estor most. One syllable adjectives like big and fast tend to prefer -er and -est.Larger ones like beautiful and carefully take more and most.
