• Short adjectives ending in -y: Change -y ～へ -ier. 例えば、, happy → happier, easy → easier.
• Adjectives/adverbs with two or more syllables: 使用方法 more before the word. For example, beautiful → more beautiful, carefully → more carefully.
• Some two-syllable adjectives: Can use either -er または more （例：, clever → cleverer / more clever).

What About "Less" and "Least"?

Less そして least are the opposites of more そして most.
