When do we use the comparative form of adjectives and adverbs?
When do we use the superlative form of adjectives and adverbs?

•  We form comparative and superlative degrees of Adjectives and Adverbs. Usually, adjectives with one syllable form their comparatives adding er; and est for superlatives.
•  We also use er and est for two-syllabled adjectives that end in y. We replace y with i.
•  For adjectives of more than two syllables, we add more and most
•  For adverbs ending in ly we use more and most to form their comparatives and superlatives respectively.
•  We can use either er/est or more/most with some two-syllabled adjectives especially quiet, clever, narrow, shallow, simple.
•  Some adjectives and adverbs have irregular comparative and superlative forms.
