Superlative adjectives help us describe one thing as the extreme in a group of three or more. We use them to say something is ‘the most’ or ‘the least’ of its kind. For short adjectives, we usually add -est to the end, like tallest 或 oldest. Remember to always put the before the superlative adjective. For longer adjectives, we put the most 或 the least in front of the adjective, for example, the most popular. These adjectives are very common in everyday English and are important for the A2 Key exam. They allow you to compare items and highlight the one that stands out in a group.

What Are Superlative Adjectives?

Superlative adjectives help us compare three or more things. They show which thing is at the top or bottom of a quality.

For example, if you have three friends, one might be the tallest. Or, if you visit many cities, one might be the most beautiful.

Superlatives in the A2 Key Exam

Superlative adjectives are important for the A2 Key (KET) exam. You might see them in Reading and Writing Part 5, where you choose the correct word to complete a sentence.

You may also need to use them correctly in Writing Part 6, when you write a short message or email.

tall taller the tallest
big bigger the biggest
happy happier the happiest
popular more popular the most popular
good better the best

西班牙语母语者常犯的错误

  • Forgetting 'the': A common mistake for Spanish speakers is forgetting to use the before the superlative adjective. In English, we always say the biggest, ,而不仅仅是 biggest.
  • Using 'more' instead of 'most': For long adjectives, remember to use the most, 而不是 the more. 例如,, the most popular (correct) instead of the more popular (incorrect).
  • Adding '-est' to long adjectives: Do not add -est to long adjectives. For example, the most beautiful (correct) instead of the beautifulest (incorrect).
  • Incorrect spelling: Be careful with spelling rules, like doubling the consonant in big to make biggest, or changing -y 到 -i 用于 happiest.

常见问题

比较级和最高级的形容词有什么区别?

比较级形容词用于比较两样事物(例如,, taller). Superlative adjectives compare three or more things and show the extreme (e.g., the tallest).

Can I use 'very' with superlative adjectives?

No, we do not use very with superlative adjectives. Superlatives already express the highest degree. You can use words like by far 或 much to emphasize, for example, It's by far the best book.

Are there any adjectives that don't have a superlative form?

Some adjectives describe absolute qualities and usually don't have superlative forms, like dead, unique, 或 perfect. Something is either dead or not, it cannot be the deadest.

How are superlatives tested in the A2 Key exam?

In the A2 Key exam, you might find superlatives in 'Reading and Writing Part 5: Multiple-choice cloze'. You need to choose the correct word (often a superlative form) to complete a sentence. For example, choosing the biggest from options like bigger, big, the biggest.
