COMPARATIVE and SUPERLATIVE OF ADJECTIVES
To compare the qualities of two people or things, we use comparative adjectives.
adjective + er
To compare a person or thing within a group, we use superlative of adjectives.
This bag is the least expensive in the store.
small + er tall + er cold + er light + er heavy + er lucky + er easy + er
heavier luckier easier
one syllable
two syllables end in -y
COMPARATIVE ADJECTIVES
small + est tall + est cold + est light + est heavy + est heaviest lucky + est easy + est luckiest easiest

Add -st: widest, finest, cutest Double the consonant, and add -est: hottest, biggest, fattest, saddest Change y to i, then add -est: happiest, silliest, loneliest, jolliest Add -est: yellower, simpler
However, the majority of adverbs do not take these endings. Instead, they form the comparative using more and the superlative using most:
Adverb recently effectively frequently Comparative more recently more effectively more frequently Superlative most recently most effectively most frequently
sadder bigger fatter
saddest biggest fattest
Rule 4
To form the comparative or superlative of a two syllable word ending in y, change the y to i, then add -er OR -est.
The bird sings loudly. The moose sang louder than the bird. Pete sang the loudest of them all.

Comparative and superlative adjectivesThe comparative form of an adjective is used for comparing two people or things (e.g. he is taller than me), while the superlative is used for comparing one person or thing with every other member of their group (e.g. he was the tallest boy in the class).Adjectives make their comparative and superlative forms in different ways, depending on the base adjective itself.
