2. How are comparative and superlative adjectives made? 

In order to build comparative and superlative structures, some rules must be followed:

  • One-syllable adjectives usually form the comparative by adding the ending -er to the adjective, and the superlative by adding the ending -est. The article the usually precedes a superlative.

    Adjectives ending in consonant + vowel + consonant The last consonant is doubled and then -ER is added The last consonant is doubled and then -EST is added

  • Two-syllable adjectives usually form the comparative by placing the particle more before the adjective, and the superlative by placing the particle the most. The adjective doesn't suffer any changes. The -er and -est forms can also be used instead, but it's less common.
