Adjective + er
Adjectives of one syllable – fast, large, big
Add er at the end of the adjective: fast → faster
If the adjective ends with the letter e, only add r: large → larger
If the adjective ends with vowel-consonant, double the final consonant before
adding er: big → bigger
not adjective + er
We normally use the opposite adjective instead of using not adjective + er. So for
example we would not say;
An old computer is not faster than a new one.
We would either say;
An old computer is slower than a new one.
or
A new computer is faster than an old one.
Adjectives of two syllables, ending in ‘y’ – heavy, dirty, ugly
Replace y with i then add er: heavier, dirtier, uglier
not adjective + ier
We normally use the opposite adjective instead of using not adjective + ier.
So for example we would not say;
A laptop is not heavier than a desktop.
We would either say;
A desktop is heavier than a laptop.
or
A laptop is lighter than a desktop.
* The word yours is a possessive pronoun and is used here to replace the phrase your screen. This is to avoid repeating the word screen.
Adjectives of more than two syllables – expensive, powerful
not more / not less
We often use the opposite adjective instead of using not more / not less.
So for example we would not say;
A laptop is not more expensive than a desktop.
We would either say;
A laptop is more expensive than a desktop.
or
A desktop is cheaper than a laptop.
Irregular comparative adjectives – good / bad
To make comparisons with the adjectives good or bad, we do not add er but use the words better and worse.
