How to form the comparative forms of adverbs
Some adverbs recognize degrees of comparison.
Adverbs consisting of one or two syllables form their comparative and superlative forms by adding –er and –est.
Examples are given below.
Long -> longer -> longest
Fast -> faster -> fastest
Early -> earlier -> earliest
Some adverbs have irregular forms for the comparative and the superlative.
Well -> better -> best
Late -> later -> latest
Little -> less -> least
Much -> more -> most
Adverbs with three or more syllables form their comparative and superlative forms by adding ‘more’ and ‘most’.
Beautifully -> more beautifully -> most beautifully
Conveniently -> more conveniently -> most conveniently
The use of the degrees of comparison
To make comparisons using positive adverbs we use the structure as…as…
Women can work as efficiently as men.
In negative comparisons not so/as…as is used.
