good - better - best

A small number of adjectives are irregular in the way they make comparative and superlative forms.

The normal (regular) way to make comparative and superlative adjectives is to add -er/-est or use more/most, like this:

• big → bigger → biggest
• expensive → more expensive → most expensive

Irregular adjectives use completely different forms. Note, however, that some adjectives can be both regular and irregular, sometimes with a slight change in meaning. The most important irregular adjectives are listed in the table below.
