6.32 irregular forms

Some very common adverbs have comparatives and superlatives that are single words and not formed using 'more' and 'most'. Note that adverbs that have irregular comparatives also have irregular superlatives.

'Well' has the comparative 'better', and the superlative 'best'.

'Badly' has the comparative 'worse' and the superlative 'worst'.

Note that 'worse' and 'worst' are also the comparative and superlative of 'ill' when it is an adverb or adjective.
