Comparative Adjectives

Comparative adjectives show how one thing differs from another in size, quality, or degree. They help you compare two (or sometimes more) things clearly and precisely.

Formation

Most short adjectives form the comparative by adding -er, and longer adjectives use more before the adjective. Some adjectives change in special ways, so it helps to learn common exceptions.

Adding -er

Short adjectives that end in a single consonant often double the consonant when you add -er. This keeps the pronunciation clear and follows English spelling rules.

Using more

Longer adjectives, especially those with two or more syllables, form the comparative with more rather than adding -er. This sounds natural and keeps the adjective intact.

Double -er / more exceptions

Some two-syllable adjectives can use either -er or more, depending on style or emphasis. Adjectives ending in -y usually change to -ier, and a few adjectives resist comparatives and use other forms instead.
