Comparatives
Level A2 · bigger · more expensive
How do you compare two things?
To compare two people or things, English changes the adjective and adds than. Short adjectives take -er; long ones take more.
When you use it
- Shopping: This one is cheaper.
- Describing: My city is bigger than yours.
Pattern
short: adj-er + than · long: more + adj + than
Examples
- Trains are **faster than** buses. — fast → faster
- Gold is **more expensive than** silver. — long adjective → more
Watch out: Never both: not “more cheaper”. And remember good → better, bad → worse.
The rule
Short adjectives add -er (cheap → cheaper). Long adjectives use more (more expensive). Then use than.
Irregular: good → better, bad → worse, far → further
Compare: My car is fast. → My car is faster than yours.
Tip
Spelling: big → bigger, happy → happier, nice → nicer.
Common mistakes

more cheap— But: cheaper - Not:
