Use the adjectives in the correct form - English grammar worksheet.

Let’s go through each sentence one by one. We need to use the comparative form of the adjectives because every sentence has the word “than” — that means we’re comparing two things.

Here’s how to make comparatives:
- For short adjectives (1 or 2 syllables), usually add -er:
→ large → larger, nice → nicer, old → older
- If it ends in “y”, change “y” to “i” and add -er:
→ happy → happier, heavy → heavier
- For longer adjectives (3+ syllables), use more + adjective:
→ difficult → more difficult, interesting → more interesting
- Some are irregular:
→ good → better, bad → worse (but none here)

Now let’s solve each:

---

1.
a. “large” → larger
b. “nice” → nicer
c. “safe” → safer

2.
a. “old” → older
b. “clean” → cleaner
c. “strong” → stronger
d. “cold” → colder
e. “young” → younger
f. “thick” → thicker

3.
a. “big” → bigger (double the ‘g’!)
b. “thin” → thinner (double the ‘n’!)
c. “hot” → hotter (double the ‘t’!)

4.
a. “easy” → easier (change y to i)
b. “angry” → angrier (change y to i)
c. “happy” → happier (change y to i)
d. “dirty” → dirtier (change y to i)
e. “ugly” → uglier (change y to i)
f. “heavy” → heavier (change y to i)

5.
a. “difficult” → more difficult (long word)
b. “interesting” → more interesting (long word)
