Comparatives & Superlatives

cheaper, more convenient, the best — how to compare options correctly. Essential for Speaking Task 5 and Writing Task 2 (choosing between two options).

6 min read
Key strategies
  • 1.Short adjectives add -er / -est: cheap → cheaper → the cheapest.
  • 2.Long adjectives (2+ syllables) use more / most: convenient → more convenient → the most convenient.
  • 3.Use "than" with comparatives: "A is cheaper THAN B." Use "the" with superlatives: "the best option".
  • 4.Irregulars: good → better → best; bad → worse → worst; far → further → furthest.

Comparatives (comparing two)

  • Short adjectives (one syllable, or two ending in -y): add -er, and change -y to -ier:
    • cheap → cheaper, big → bigger, easy → easier.
  • Longer adjectives: use more:
    • expensive → more expensive, comfortable → more comfortable.

Always pair a comparative with than:

"The train is faster than the bus." "This option is more practical than that one."

Superlatives (comparing three or more)

  • Short: -est with the: the cheapest, the biggest.
  • Long: the most: the most expensive, the most reliable.

"It is the best choice for our budget."

Irregular forms (memorise)

good → better → best · bad → worse → worst · far → further/farther → furthest/farthest · little → less → least · much/many → more → most.

Avoid double comparatives: ✗ "more cheaper" → ✓ "cheaper".

CELPIP application

Speaking Task 5 (Comparing & Persuading) and Writing Task 2 are built on comparison. Confident comparatives make your case: "The cabin is cheaper and more relaxing than the hotel, so it is the better choice for us."
