Adjectives in English

positive form of the adjective. For example: fast - faster 

strong - stronger 
tall - tallest  young - youngest

When an adjective ends in a silent e, the silent e is dropped before the ending er/est is added.
e.g.:  brave - braver - bravest 
close - closer - closest
late - later - latest

the y is changed to i before the ending er/est

is added.
e.g.:  dry - drier-driest;   easy - easier-easiest
When an adjective ends in a CVC and the last consonant is other than w, x or y or a double vowel - we double the final consonant before adding er/est is added.
e.g.:  big - bigger-biggest  (hot - hotter  sad - saddest
but:
e.g.: loud - louder;  neat - neater;  soon - sooner
