Comparative adjectives help us compare two nouns (people, places, or things) and show how they are different. We use them to say one thing has more of a quality than another. For short adjectives (one syllable), we usually add -er, come tall becomes taller. If the adjective ends in -y, we change -y a -i and add -er, ad esempio, happy becomes happier. For longer adjectives (two or more syllables), we put more before the adjective, for example, expensive becomes more expensive. After the comparative adjective, we often use than to introduce the second item in the comparison. For instance, My car is older than your car. This structure is essential for clear comparisons in English at an A2 level, allowing you to describe differences simply and effectively.

What are comparative adjectives?

Comparative adjectives are special words that help us compare two things. They show how one thing is different from another in terms of a specific quality.

For example, if you have two books, you can say This book is bigger than that book.

How do we form comparative adjectives?

The way we form a comparative adjective depends on the number of syllables in the original adjective:

  • Short adjectives (one syllable): Aggiungi -er to the end. If the adjective ends in a consonant-vowel-consonant (CVC) pattern, double the last consonant before adding -er.
    • oldolder
    • fastfaster
    • bigbigger (CVC: b-i-g)
    • hothotter (CVC: h-o-t)
  • Adjectives ending in -y (usually two syllables): Change the -y a -i and then add -er.
    • happyhappier
    • easyeasier
  • Long adjectives (two or more syllables, not ending in -y): Put the word more before the adjective.
    • beautifulmore beautiful
    • interestingmore interesting
    • expensivemore expensive

What about irregular comparative adjectives?

Some common adjectives have special, irregular comparative forms. You need to learn these by heart:

  • goodbetter
  • badworse
  • farfarther / further
  • little (amount) → less
  • much/manymore

When do we use 'than'?

Utilizziamo than after a comparative adjective to introduce the second item in the comparison. It helps to clearly show what two things you are comparing.

  • My new phone is faster than my old one.
  • This movie is more exciting than that TV show.

Sometimes, if it is very clear from the situation, you can leave out than and the second item. For example, if someone asks, "Do you like this coffee or that coffee?" you can just say, This one is better.

Domande frequenti

Can I use "less" with comparative adjectives?

Yes, you can use less for the opposite meaning of more. Ad esempio, This book is less interesting than that one. È possibile utilizzare less with all adjectives, both short and long.

Do I always need to use "than" after a comparative adjective?

Not always. You use than when you explicitly mention the second item you are comparing. If the second item is clear from context, you can omit than. For example, if someone asks, "Which shirt do you prefer?" you can simply say, The blue one is nicer.

How are comparative adjectives important for the A2 Key exam?

Comparative adjectives are very useful in the A2 Key exam, especially in the Speaking Part 1 or 2, where you might need to describe people, places, or things and compare them. For example, you might say My town is smaller than the capital city. oppure This activity is more fun.
