A. Look at these examples:
How shall we travel? By car or by train?
Let's go by car. It's cheaper.
Don't go by train. It's more expensive.
Cheaper and more expensive are comparative forms.
After comparatives you can use than (see also Unit 106):
* It's cheaper to go by car than by train.
* Going by train is more expensive than going by car.
B. The comparative form is ~er or more...
We use ~er for short words (one syllable):
cheap -> cheaper, fast-> faster, large -> larger, thin -> thinner
We also use ~er for two-syllable words that end in -y (-y -> -ier):
lucky -> luckier, early -> earlier, easy -> easier, pretty -> prettier
For spelling, see Appendix 6.
Compare these examples:
* You're older than me.
* The exam was quite easy - easier than we expected.
* Can you walk a bit faster?
* I'd like to have a bigger car.
* Last night I went to bed earlier than usual.
We use more... for longer words (two syllables or more):
more modern, more serious, more expensive, more comfortable
We use more... for adverbs that end in -1y:
more slowly, more seriously, more quietly, more carefully
Also: more often
but: earlier (not 'more early')
* You're more patient than me.
* The exam was quite difficult - more difficult than we expected.
* Can you walk a bit more slowly?
* I'd like to have a more reliable car.
* 1 don't play tennis much these days. I used to play more often.
You can use ~er or more... with some two-syllable adjectives, especially:
quiet, clever, narrow, shallow, simple
* It's too noisy here. Can we go somewhere quieter/more quiet?
C. These adjectives and adverbs have irregular comparative forms:
good/well -> better:
* The garden looks better since you tidied it up.
* I know him well - probably better than anybody else.
bad/badly -> worse:
* 'Is your headache better?' 'No, it's worse.'
* He did very badly in the exam - worse than expected.
far --> further (or farther):
* It's a long walk from here to the station - further than I thought.(or...farther than...) Further (but not 'farther') can also mean 'more' or 'additional':
* Let me know if you hear any further news. (= any more news)
