Let’s go through each sentence one by one. We need to use the
superlative form of the adjective in parentheses. That means we’re talking about “the most” or “the least” of something — like “the highest,” “the fastest,” etc.
Here’s how superlatives usually work:
- For short adjectives (1–2 syllables), add
-est → e.g., high → highest
- For longer adjectives (3+ syllables), use
most + adjective → e.g., expensive → most expensive
- Some are irregular → e.g., bad → worst, good → best
Now let’s solve each:
1. Burj Khalifa is
the highest building in the world. (high → highest)
2. Cheetah is one of
the fastest animals on Earth. (fast → fastest)
3. A Bugatti is
the most expensive Italian car. (expensive → most expensive)
4. February is
the shortest month of the year. (short → shortest)
5. Football is
the most popular sport in Spain. (popular → most popular)
6. I am
the youngest person in my family. (young → youngest)
7. Maggie is
the prettiest girl in my class. (pretty → prettiest — note: y changes to i before -est)
8. Puppies are
the cutest animals of all. (cute → cutest)
9. Polish is one of
the most difficult languages to learn. (difficult → most difficult)
10. It was
the tastiest pasta I have ever eaten. (tasty → tastiest — y to i)
11. Mike got
the worst score on the Maths test. (bad → worst — irregular!)
12. Susan is
the friendliest person I’ve ever known. (friendly → friendliest — y to i)
13. This armchair is
the most comfortable in my house. (comfortable → most comfortable)
14. Koalas are one of
the laziest animals in the world. (lazy → laziest — y to i)
15. Skydiving is one of
the most dangerous sports. (dangerous → most dangerous)
16.

17. My mum was wearing
the most elegant dress. (elegant → most elegant)
