Let’s go step by step through each sentence. We need to turn the adjective in parentheses into its
superlative form — that means “the most” or “the -est” version of the word, because we’re talking about one thing being *more than all others*.
We’ll use the rules from the boxes at the top:
- 1 syllable → add
-est (or sometimes just -st if it ends in ‘e’)
- 2+ syllables → usually add
most before the word
- Ends in ‘y’? Change ‘y’ to ‘i’ and add
-est
- Ends in single vowel + consonant? Double the last letter, then add
-est
- Irregulars: good → best, bad → worst, far → farthest/furthest
---
Now let’s solve each one:
1. I (tall) →
am the tallest person in my family.
✔ Already done correctly.
2. Jupiter (big) → big is 1 syllable →
biggest
→ Jupiter is the
biggest planet in our solar system.
3. Elephants (large) → large ends in ‘e’, so just add -st →
largest
→ Elephants are the
largest land animals on earth.
4. We bought (expensive) → expensive has 3 syllables → use
most expensive
→ We bought the
most expensive TV in the store.
5. Which sports do you think (dangerous)? → dangerous = 3 syllables →

6. My cat (lazy) → lazy ends in ‘y’ → change to ‘i’ + est →
laziest
→ My cat is the
laziest animal I know.
7. This restaurant serves (good) → irregular! good →

best food in town.
8. I think math (difficult) → difficult = 3 syllables →
