Use:
We use the comparative form to talk about how two things are different.
Planes are faster than trains.
Planes are actually safer than cars.
A bus is bigger than a car.
A motorbike is noisier than a bike.
Cycling is more dangerous than walking.
Form:
1) If an adjective has one syllable, add er to the end. If it ends in e already, just add r.
slow => slower safe => safer
quick => quicker nice => nicer
2) If an adjective ends in one vowel and one consonant, write the consonant again, then write er. But never write a w, x or y twice.
big => bigger thin => thinner slim => slimmer fat => fatter
new => newer (NOT newwer) slow => slower (NOT slowwer)
My brother is thinner than me. The black boat is slower than the white one.
3) If an adjective has two syllables and ends in y, change the y to i and add er.
funny => funnier silly => sillier
Which of these books is funnier?
4) If an adjective has two syllables (and does not end in y) or more than two syllables, we use more before the adjective
His car is more modern than mine.
5) Some adjectives have irregular superlative forms. These are listed below.
good => better
bad => worse
far => further
Add than after a comparative adjective to compare one thing with another. However, this is not always necessary.
My house is smaller than yours.
Alice's bike is older, but yours is even older!
