Comparatives and Superlatives: Rules

Comparatives contrast things; superlatives identify an extreme within a group. Adjectives use different ending patterns, more/most or irregular forms.

Want to compare things? Use comparatives for comparing 2 things and superlatives for comparing 3 or more! Let's learn all the rules. 📊

Comparative: Comparing Two Things

Use comparatives when comparing TWO things. Add -er for short adjectives or use more for longer ones. Use than when stating the other side of the comparison; it can be omitted when that comparison is understood.

💡 Short adjective: tall → taller

💡 Long adjective: more + interesting

💡 Double consonant: hot → hotter

💡 Long adjective: more exciting

Superlative: Comparing Three or More

Use superlatives when comparing THREE or more things. Add -est for short adjectives or use most for longer ones. The often comes before a superlative, but a possessive can replace it: my best friend.
