Much Faster, More Expensive

Comparatives: -er or more / less, and where much goes

Level 2 — Grammar

Look at These Three Sentences

All three compare two things. Look at the colored part.

She is faster than her father.
That car is more expensive than those shoes.
The pencil is less expensive than the car.

Why faster but more expensive? Two questions answer everything:

1. How many syllables is the adjective?
2. Is the difference big or small? (That tells you if you need much.)

Rule 1 — Count the Syllables

AdjectiveRuleExamples
Short
(1 syllable)
add -erfast → faster
cheap → cheaper
tall → taller
Long
(2 or more syllables)
more ___
less ___
expensive → more / less expensive
comfortable → more / less comfortable
interesting → more / less interesting
2 syllables
ending in -y
change y to i,
add -er
happy → happier
busy → busier

Class: clap the beats. One clap = -er. Two or more claps = more / less (but -y words: happier). Then sort the words on the next slide.

Clap and Sort

Clap the syllables. Call out -er or more / less. Then click the card to check.

1. heavy

-er column: heavier — heav-y: 2 syllables, ends in -y.

2. expensive

more / less column: more expensive — ex-pen-sive: 3 syllables.

3. dangerous

more / less column: more dangerous — dan-ger-ous: 3 syllables.

4. slow

9. powerful

10. short

Rule 2 — Where Does "much" Go?

[A] + is + much + faster / more expensive / less expensive + than + [B]

much goes right before the comparative. Nowhere else.

Wrong: The bus is more faster than the train.
Wrong: The bus is faster much than the train.
Wrong: The bus is much expensiver than the train.

Use much only for a BIG difference. No much = a normal or small difference.

Build It Step by Step

Start: The laptop is expensive. Say each step out loud, then click.

Step 1. Make it a comparative. Compare it to the phone.

The laptop is more expensive than the phone. ex-pen-sive = 3 syllables, so more, not -er.

Step 2. The difference is big. Add much.

The laptop is much more expensive than the phone. much goes right before more.

Step 3. Now flip it. Start with the phone and use less.

The phone is less expensive than the laptop. Same facts, opposite direction.

Step 4. Add much to the flipped sentence.

The phone is much less expensive than the laptop. much + less + adjective.
