The superlative form of an adverb is used to say what thing or person does something to the greater degree within a group or of its kind. Superlatives can be preceded by 'the'. In general the superlative forms of adverbs are the same as for superlative forms of adjectives.
The rule for forming the superlative of an adverb is if it has the same form as an adjective add the suffix -est to the end.
- fast - "Jill ran the fastest."
When an adverb ends in -ly, most is put in front of the adverb.
- Frequently - "Jill did her homework most frequently."
The following irregular adverbs are exceptions:-
- 'well' becomes 'the best'
- 'badly' becomes 'the worst'
- "Jill did the best in the test."
- "Jack did the worst in the test."
