Regular Comparatives and Superlatives

Comparatives and Superlatives are special forms of adjectives. They are used to compare two or more things. Generally, comparatives are formed using -er and superlatives are formed using -est. This page will explain the rules for forming regular comparatives and superlatives, and also show some basic ways of using them.

Forming regular comparatives and superlatives

How these forms are created depends on how many syllables there are in the adjective. Syllables are like "sound beats". For instance, "sing" contains one syllable, but "singing" contains two -- sing and ing. Here are the rules:
Adjective form
Comparative
Superlative
Only one syllable, ending in E. Examples:
wide, fine, cute 		Add -R:
wider, finer, cuter 		Add -ST:
widest, finest, cutest
Only one syllable, with one vowel and one consonant at the end. Examples:
hot, big, fat 		Double the consonant, and add -ER:
hotter, bigger, fatter 		Double the consonant, and add -EST:
hottest, biggest, fattest
Only one syllable, with more than one vowel or more than one consonant at the end. Examples:
light, neat, fast 		Add -ER:
lighter, neater, faster 		Add -EST:
lightest, neatest, fastest
Two syllables, ending in Y. Examples:
happy, silly, lonely 		Change Y to I, then add -ER:
happier, sillier, lonelier 		Change Y to I, then add -EST:
happiest, silliest, loneliest
Two syllables or more, not ending in Y. Examples:
modern, interesting, beautiful 		Use MORE before the adjective:
more modern, more interesting, more beautiful 		Use MOST before the adjective:
most modern, most interesting, most beautiful

How to use comparatives and superlatives

Comparatives
 Comparatives are used to compare two things. You can use sentences with THAN, or you can use a conjunction like BUT. Examples:
  • Jiro is taller than Yukio.
  • Yukio is tall, but Jiro is taller.
Superlatives
 Superlatives are used to compare more than two things. Superlative sentences usually use THE, because there is only one superlative. Examples:
  • Masami is the tallest in the class.
  • Yukio is tall, and Jiro is taller, but Masami is the tallest.
