Comparative and Superlative Adjectives in English Grammar


Comparative adjectives, such as bigger or better, compare two nouns. We can use them to express that a person or thing has less or more of something. Superlative adjectives, such as biggest or best, compare one person or thing against a whole group. We can use superlatives to express that a noun has more of something than everything else in that group. Regular comparative and superlative adjectives are formed with the suffixes -er/est or the adverbs more/most. The irregular forms have to be learnt by heart.

This clown’s funny. He’s the funniest clown I have ever seen.

The clown’s got a big nose. His nose is much bigger than mine.



Adjectives describe nouns.

This clown is funny.
The clown has got a big nose.

Adjectives also have comparative forms.

His nose is much bigger than mine. (comparative)
He is the funniest clown I have ever seen. (superlative)

Adjective Order

We use adjectives before nouns and after the verb be. We can use more than one adjective to describe things.

  • We usually put opinion adjectives (beautiful, funny, nice, ugly etc.) before fact adjectives (small, young, pink, plastic etc.).
    The clown has an ugly red nose.
  • Sometimes we use more than one fact adjective. We usually put fact adjectives in the same order.
    The clown has a big red plastic nose. (not: The clown has a red plastic big nose.)

The table shows you the correct order for adjectives.

Forming Comparative and Superlative Adjectives

Comparative using er/est

We form the comparative adjectives of most single and two-syllable adjectives by adding the suffix -er. The Superlative form is constructed with the suffix -est.The table below provides an overview of single and two-syllable adjectives in the basic, comparative and superlative form.

basic form comparative superlative
all single-syllable adjectives clean cleaner the cleanest
two-syllable adjectives that end in y easy easier the easiest

Exceptions when adding er/est

  • Add -r/-st to adjectives that end in -e.
    late – later – the latest (not: lateer– the lateest)
  • A -y at the end of an adjective becomes an -i.
    easy – easier – the easiest
  • The final consonant is doubled in adjectives that end with a consonant after a short stressed vowel.
    hot – hotter – the hottest

Comparative using more and most

The comparative form of multi-syllable adjectives is constructed with more and the basic form of the adjective. Whilst the superlative form is constructed with most and the basic form of the adjective. The table below provides an overview of multi-syllable adjectives in the basic, comparative and superlative form.

basic form comparative superlative
all multi-syllable adjectives
(except two-syllable ones ending in -y/-er)

Comparative using er/est or more/most

Some two-syllable adjectives can be formed with either -er/-est or more/most. Theses include primarily two-syllable adjectives that end in -er.

Adjectives That Can't Be Compared

Some adjectives are gradable and some are non-gradable.

  • We can modify gradable adjectives to express different levels.
    The clown yesterday was funny, but the clown on TV is funnier and the one from last week was the funniest.
  • Non-gradable or extreme adjectives do not have a comparative or superlative form because they mean very funny, very big etc. Or because they express something which cannot be graded dead or pregnant.
    The clown is hilarious (very funny). not: The clown is more hilarious than you.
    The clown has a huge (very big) red nose. not: The clown has the hugest red nose.
    I think the clown is pregnant. not: The clown is more pregnant than yesterday.

Some common extreme adjectives include: empty, full, alive, dead, pregnant, perfect, unique, round, square, awful, excellent, terrible, horrible, chemical, digital, domestic, immortal, starving, brilliant, gigantic, ultimate, ancient, complete etc.
