Educational worksheet on comparative adjectives with rules and exercises.

Let me work through this step by step to find the comparative forms of each adjective.

First, let me recall the rules for forming comparatives:
- 1-2 syllables ending in consonant-vowel-consonant: double last consonant + er (big → bigger)
- 1-2 syllables ending in -y: change y to i + er (happy → happier)
- 1-2 syllables: add -er (tall → taller)
- 3+ syllables: use "more" before the word (beautiful → more beautiful)
- Irregular forms must be memorized (good → better, bad → worse, etc.)

Now let me solve each one:

1. ugly → uglier (ends in -y, so change to -ier) ✓ (already given)
2. happy → happier (ends in -y)
3. smart → smarter (1 syllable, add -er)
4. friendly → friendlier (ends in -y)
5. beautiful → more beautiful (3 syllables, use "more")
6. peaceful → more peaceful (2 syllables but ends in -ful, use "more")
7. strange → stranger (1 syllable, add -r since it ends in e)
8. silly → sillier (ends in -y)
9. dirty → dirtier (ends in -y)
10. wet → wetter (1 syllable, CVC pattern, double t)
11. funny → funnier (ends in -y)
12. clean → cleaner (1 syllable, add -er)
13. filthy → filthier (ends in -y)
14. crazy → crazier (ends in -y)
15. intelligent → more intelligent (4 syllables, use "more")
16. brave → braver (1 syllable, ends in e, just add -r)
17. courageous → more courageous (3 syllables, use "more")
18. pretty → prettier (ends in -y)
19. sad → sadder (1 syllable, CVC pattern, double d)
20. colorful → more colorful (3 syllables, use "more")
21. tasty → tastier (ends in -y)
22. sloppy → sloppier (ends in -y)
23. cold → colder (1 syllable, add -er)
24. careful → more careful (2 syllables ending in -ful, use "more")
25. close → closer (1 syllable, ends in e, add -r)
26. thin → thinner (1 syllable, CVC pattern, double n)
27. bright → brighter (1 syllable, add -er)
28. young → younger (1 syllable, add -er)
29. fast → faster (1 syllable, add -er)
