Spanish has a couple of adjectives and adverbs that are exceptions when it comes to forming the comparative and superlative.
As adjectives, bueno (good), malo (bad), grande (big), and pequeño (small) have irregular forms in the comparative and superlative. Note that grande and pequeño each have two different meanings in their comparative and superlative forms.
