Comparatives are used to compare two things or people. For short adjectives, typically those with one or two syllables, you add -er to the end of the word, like tall becomes taller and small becomes smaller. For words which end in -y, you change the y to i and add -er, like happy becomes happier.
Examples:
He is taller than his brother. - Taller is the comparative form of tall, used because the speaker is comparing the height of two people.
This box is smaller than that one. - Smaller is the comparative form of small, used to compare the size of two boxes.
Which of the following sentences correctly uses a comparative form?
This computer is more fast than the old one.
Fast is a one-syllable adjective, so the correct comparative form is faster, not more fast.
She is smarter than her classmate.
He can run more quick than me.
Quick is a one-syllable adjective; the correct comparative form is quicker, not more quick.
I am more happier today than yesterday.
Happy has two syllables but generally follows the rule for short adjectives; the correct form is happier, not more happier.
