Lesson A

Comparatives

Change an adjective into the comparative form to compare two things:

Your car is faster than mine.

These socks are smaller than those ones.

This book is more interesting than my last one.

My phone is better than yours.

The comparative form is often followed by than. You can also add much to make the comparison stronger:

These socks are much smaller than those ones.

My phone is much better than yours.

Spelling rules:

• Add -er to short adjectives to form the comparative: young - younger

• When the adjective ends in -e, add -r: large - larger

• Change adjectives ending in -y (after a consonant) to -i and add -er: happy-happier

• Double the final consonant on some adjectives ending with a vowel and a consonant: hot - hotter, big - bigger .

• Add more or less before adjectives with two or more syllables: interesting-more / less interesting
