The essential rules

Short adjectives

Most one-syllable adjectives take -er/-est. Double a final consonant after one vowel; change final y to i.

small → smaller → smallest · big → bigger → biggest

Long adjectives

Use more/most with most adjectives of two or more syllables. Use than after a comparative.

more reliable than · the most convenient option

Equality and degree

Use as…as for equality and modifiers such as much, far, a little before comparatives.

as fast as · far better · a little more expensive
