Comparatives
We use comparative adjectives to compare two people, things, or groups.
There are three groups of adjectives:
tall + ertaller
fine + erfiner
big + erbigger
happy + erhappier
In one-syllable adjectives that end with a consonant-vowel-consonant (CVC) pattern, such as "big", we double the final consonant before adding "-er" to form the comparative.
In one-syllable and two-syllable adjectives that end in "y", such as "happy", we change the final "y" to "i" before adding "-er" to form the comparative.
more + modernmore modern
more + expensivemore expensive
goodbetter
badworse
littleless
farfarther / further
We usually use the preposition "than" after a comparative structure.
She's taller than her sister.
This book is more interesting than that one.
