Unit 8.2

Superlative of Adjectives and Adverbs



The superlative adjectives/adverbs are used to make a comparison between things, people or actions, expressing the superiority of one thing, person or action which has the highest level of a particular quality.


The superlative can be formed by using adjectives or adverbs. The determiner the comes before the adjective/adverb to show that something is superior to other things.

The structure of the sentence is:
Subject + verb + the + superlative adjective/adverb + noun/adjective + …

The superlative form of an adjective/adverb is obtained differently depending on its number of syllables and on its suffix.

One syllable:

  • adjective/adverb: we add –est (clean ⇒ cleanest);
  • adjective/adverb with suffix –e: we add -st (simple ⇒ simplest);
  • adjectives ending with one vowel and one consonant: we double the final consonant before adding -est (big ⇒ biggest).

Two syllables (with suffix -y):

  • adjective/adverb with suffix -y: change -y to –i and add –est (friendly ⇒ the friendliest).

Two syllables (without suffix-y) or more syllables:

  • adjective/adverb without suffix -y: we add the most before the adjective/adverbthe most + adjective/adverb (without changes) (beautiful ⇒ the most beautiful).

When we use the most, the form of adjectives/adverbs remains the same.


  • I have the cleanest room in the house.
  • The simplest solutio is almost always the best. 
  • Jupiter is the biggest planet.
  • You are the funniest woman alive.
  • She is the friendliest girl I’ve ever met.
  • We wake up the earliest to take shower.
  • I think that tennis is the most boring sport.
  • ‘War and Peace’ is the most difficult Russian book to read.
  • Far east countries’ languages are the most popular to learn.


We use superlative adjectives/adverbs when we want to express the superiority of one thing, person or action over the others in a certain aspect.


We use superlative adjectives/adverbs when we make a comparison between things, people or actions, expressing the superiority of one that has the highest level of a particular quality.

When we use superlative adjectives or adverbs, we start with the subject and the verb followed by the and the superlative adjective or adverb, followed by a noun or an adjective.

Their form differs according to the number of syllables and the suffix of the adjective.

For example:
— We add -est at the end of the word: “Tall” ⇒ “Claire is the tallest girl in the class.
— With suffix -e, we add -st: “Nice” ⇒ “Anne is the nicest girl I know.
— With one vowel + one consonant, we double the consonant and add -est: “Thin” ⇒ “Karl is the thinnest.”

— With suffix -y, -y becomes -i, and we add -est: “Hungry ⇒ “Claire is the hungriest girl in the class.”

Two or more syllables
— (Without suffix -y) We add most before the adjective/adverb: “Tired” ⇒ “Claire is the most tired girl in the class.”
