Let’s examine these ways.

With one-syllable words: add –est to the end of the word.

  • Small = smallest
  • Green = greenest

With one-syllable words that end in an “e”: add –st to the end of the word.

  • Large = largest
  • Fine = finest

With two syllable words: add –est to the end of the word.

  • Quiet = quietest
  • Rapid = rapidest

With two syllable words that end in “y”: change the “y” to an “i” and then add –est.

  • Murky = murkiest
  • Goofy = goofiest

With three or more syllable words: add more or least before the adjective.

  • Mysterious = most mysterious

What is the Difference Between Superlative and Comparative Adjectives?

Example of Superlative vs. Comparative Adjectives:
