How to use them

For adjectives with one syllable, add er and est. Sometimes the spelling changes. Don’t forget the for the superlative.

tall – taller – the tallest

big – bigger – the biggest
My room is bigger than my sister’s room. Our parents’ room is the biggest room in the house.

For adjectives with two syllables which end in y, take away the y and add ier and iest. Don’t forget the for the superlative.

easy – easier – the easiest
Maths is easier than science. English is the easiest subject.

For other adjectives with two or more syllables, use more and most. Don’t forget the for the superlative.
