Comparative adjectives worksheet for language learners to practice filling in blanks with correct comparative forms.

Let's solve this worksheet step by step. The task is to complete the sentences using the comparative forms of the given adjectives.

We need to remember the rules for forming comparative adjectives:

1. One-syllable adjectives: Add -er (e.g., old → older).
2. Two-syllable adjectives ending in -y: Change -y to -ier (e.g., pretty → prettier).
3. Two-syllable adjectives not ending in -y and most multi-syllable adjectives: Use more + adjective (e.g., good → better, large → larger, nice → nicer).
4. Irregular adjectives: Some have irregular forms (e.g., good → better, bad → worse).

Let's go through each sentence:

1. Ruby was (old) _________ than Ken.
→ "Old" is a one-syllable adjective → add -er
✔ older

2. My house is (large) _________ than hers.
→ "Large" is a two-syllable adjective, but it follows the regular pattern → add -r
✔ larger

3. My dog runs (fast) _________ than you.
→ "Fast" is a one-syllable adjective → add -er
✔ faster

4. Cats are (nice) _________ than dogs.
→ "Nice" ends in -e → change to nicer (two syllables, ends in -e)
✔ nicer

5. Cartoons are (good) _________ TV programs.
→ "Good" is irregular → comparative is better
✔ better

6. The US is (big) _________ than Australia.
→ "Big" is one-syllable → add -ger
✔ bigger

7. June is (pretty) _________ than May.
→ "Pretty" ends in -y → change to prettier
✔ prettier

8. I think Jurassic Park was the (good) _________ film ever!
→ This is not a comparison between two things; it’s saying it's the best ever → use superlative form.
→ "Good" → superlative = best
✔ best

9. Mount Everest is (tall) _________ than Mount Abu.
→ "Tall" is one-syllable → add -er
✔ taller

10. My room is (clean) _________ than your room.

📌 Note: Question 8 uses the superlative ("the best") because it compares something to all others (ever), not just two things. That's why it's different from the rest.
