How to use the generator

Type one or several adjectives. The table shows the comparative (used to compare two things) and the superlative (used to compare three or more).

The rules

  • One syllable: add -er / -est (tall, taller, tallest)
  • Ends in -e: add -r / -st (large, larger, largest)
  • Consonant + vowel + consonant: double the last letter (big, bigger, biggest)
  • Two syllables ending in -y: change y to -ier / -iest (happy, happier, happiest)
  • Longer adjectives: use more / most (beautiful, more beautiful, most beautiful)
  • Irregular: good, better, best; bad, worse, worst; far, farther, farthest
