If you want to compare two nouns in English, you need to know the comparative form for adjectives.
For adjectives that are 1 syllable
Add -er to the end of the adjective + than
Tall – She is taller than her brother.
Short – He is shorter than his sister.
*For adjectives that ends with consonant-vowel-consonant, you usually need to double the last consonant before the -er.
Hot – In general, Florida is hotter than Vermont.
Fat – The cat is much fatter than the dog.
For adjectives that are 2+ syllables (not ending in -y)
Use more /less + adjective + than
Crowded – The bus is more crowded than the cable car.
Boring – The math teacher is less boring than the gym teacher.
For adjectives that are 2 syllables ending in -y
Change the -y to -i and add -er to the end of the adjective + than
Happy – The man looks happier than his wife.
Lucky – They are luckier than their friends.
*Of course, there are exceptions to every rule! Be careful of adjectives that take an irregular form in the comparative. Here are some examples below.
Fun – use more – It is more fun to play games than to take tests.
Narrow- add -er – The tunnel is narrower than the train.
