Theory – Comparatives and Superlatives

We use comparative adjectives when we want to compare two things or two people. Superlatives are used, however, to show the difference between more than two things or more than two people. For example: I am taller than my sister. I am the tallest woman in my family. To form comparatives and superlatives you need to know the number of syllables in the adjective. Syllables are like “sound beats”.

Perhaps one of the most important things to remember is that comparatives are almost always followed by the word ‘than’ and Superlatives are almost always preceded by the word ‘the’.

One syllable adjective ending in a silent ‘e’ – nice

  • Comparative – add ‘r’ – nicer  – Penny is nicer than Amy.
  • Superlative – add ‘st’ – nicest – Sheldon is the nicest character in the series.

One syllable adjective ending in a consonant

  • Comparative – add ‘er’ – taller – Sheldon is taller than Leonard.
  • Superlative – add ‘est’ – tallest – Sheldon is the tallest of all the characters.

One syllable adjective ending in a consonant with a single vowel before it

  • Comparative – double consonant and add ‘er’ – bigger
  • Superlative – double the consonant and add ‘est’ – biggest

Adjectives with two or more syllables that DON’T end in ‘y’

With most two-syllable and three-syllable adjectives, you form the comparative with more and the superlative with most and this is where the confusion comes in. We can never say more or most with a one syllable adjective (more good, better, most tallest, etc)

Two-syllable adjectives ending in ‘y’

The exception to the two syllable rule is that, if the adjective ends in ‘y’ we use the normal one syllable structure but change the ‘y’ to an ‘i’.

  • Comparative – happier
  • Superlative – happiest

My sister is just as bad at math as I am.
