What are Comparative Adjectives?

Comparative adjectives are words used to compare two people, things, or ideas. They show that one has more or less of a quality than the other. For example, 'taller', 'more interesting', or 'better'.

Short answer

Comparative adjectives are used to compare two items. They show that one item has more or less of a quality. Form: short adjectives add -er (tall → taller); long adjectives add 'more' (beautiful → more beautiful).

Two Ways to Form Comparatives
Short Adjectives (+er)
  • tall → taller
  • fast → faster
  • big → bigger (double last letter)
Long Adjectives ('more')
  • beautiful → more beautiful
  • interesting → more interesting
