Ans. Yes, there are some exceptions and irregularities in the formation of comparative and superlative adjectives. Some adjectives have irregular forms, such as 'good' (comparative: better, superlative: best) and 'bad' (comparative: worse, superlative: worst). Additionally, some adjectives use the words 'more' and 'most' instead of adding '-er' or '-est' to form the comparative and superlative degrees. Examples include 'beautiful' (comparative: more beautiful, superlative: most beautiful) and 'intelligent' (comparative: more intelligent, superlative: most intelligent).
