English Grammar Worksheet: Comparative & Superlative Adjectives and Adverbs

Let's solve this English Grammar Worksheet step by step, focusing on comparative and superlative adjectives and adverbs.

---

Section (1): Choose the correct words.

We need to choose the correct form of the adjective or adverb based on grammar rules:

- Comparatives: used to compare two things.
- For one-syllable adjectives: add -er (e.g., faster)
- For two-syllable adjectives ending in -y: change -y → -ier (e.g., happier)
- For most two-syllable and longer adjectives: use more (e.g., more interesting)
- Superlatives: used for three or more items.
- Add -est for one-syllable (e.g., fastest) or use the most for longer ones.
- Adverbs follow similar rules: more/less/most/least + adverb.

---

#### 1. Why do you behave less respectful / less respectfully / the least respectful these days?
- "Respectful" is an adjective; we need an adverb to modify "behave".
- "Less respectfully" is correct because it describes *how* you behave.
✔ Answer: less respectfully

---

#### 2. He’s the least / the less / least intelligent member of the family.
- Superlative form: "the least intelligent" (correct structure).
- "The less" is incorrect here — we don't say "the less intelligent".
- "Least" without "the" is incorrect in formal English.
✔ Answer: the least

---

#### 3. The boys are quieter / more quieter / more quietly than usual.
- "Quieter" is correct comparative form of "quiet" (one syllable).
- "More quieter" is double comparison — wrong.
- "More quietly" is an adverb, but the sentence needs an adjective ("are quieter").
✔ Answer: quieter

---

#### 4. If you study more hardly / hardlier / harder, you won’t fail.
- "Hardly" means "almost not", which doesn't make sense here.
- "Hardlier" is not a word.
- "Harder" is the correct comparative of "hard".
✔ Answer: harder

---

#### 5. I prefer the violin because I can carry it more easily / more easy / more easier than the guitar.
- "Easily" is the adverb form.
- "More easily" is correct comparative of the adverb.
- "More easy" and "more easier" are both incorrect.
✔ Answer: more easily

---

#### 6. Eat more slow / slowly! You should spend time enjoying your food.
- Need adverb to modify verb "eat".
- "Slowly" is the adverb form.
- "More slowly" would be correct if comparing speeds, but here it's just advising to eat slowly.
- However, "more slowly" could work in context (slower than normal), but "slowly" is acceptable.
But since it says "more slow", that’s incorrect. We want more slowly.
✔ Answer: more slowly

> Note: Some might argue "slowly" alone is enough, but since the option is "more slow / slowly", only more slowly makes grammatical sense as a comparative.

✔ Answer: more slowly

---

#### 7. He’s moodier / moodier than all my other cousins, but I still like him.
- "Moodier" is the comparative form of "moody".
- "Moodier" is correct.
- "Moodyer" is not standard English.
✔ Answer: moodier

---

#### 8. You’re the most anxious / anxiously woman I know. Don’t worry, everything will be OK!
- "Anxious" is an adjective describing the person.
- "Anxiously" is an adverb, but we need to describe the woman, not how she acts.
- So, "the most anxious" is correct.
✔ Answer: the most anxious

---

#### 9. Adam’s working the most hard / hardest. Everyone else is checking their phones.
- "Hard" is an adverb meaning effort.
- Superlative: "hardest" (not "most hard").
- "Most hard" is not correct in standard English.
✔ Answer: hardest

---

#### 10. She wanted the most expensive / expansivest dress but she didn’t have enough money.
- "Expensive" has two syllables, so we use most expensive, not "expensivest".
- "Expensivest" is not a real word.
✔ Answer: most expensive

---

#### 11. My new boss is kinder / more kind than the previous one.
- "Kinder" is the correct comparative form of "kind".
- "More kind" is possible in informal speech but not preferred.
- Standard rule: "kinder" is correct.
✔ Answer: kinder

---

#### 12. He’s the most / more optimistic person I’ve ever met.
- Comparing with all people he's ever met → superlative.
- Use the most optimistic.
- "More optimistic" would be for comparing two people.
✔ Answer: the most

---

#### 13. Would you have thanked him if he’d been more helpfully / helpful?
- "Helpfully" is an adverb; we need an adjective to describe *him*.
- "More helpful" is correct.

---

#### 14. If the roads had been less crowded, we would have driven more quickly / quicker.
- "Quickly" is the adverb form.
- "More quickly" is correct comparative form.

Section (2): Use the correct comparative or superlative form.

Use more / less / the most / the least where necessary.

---

#### 1. The person who does ____________ in the interview won’t get the job. (bad)
- "Bad" → worst → "the worst"
- But "does the worst" is awkward.
- Better: "does the least well" or "does worst"?
- Actually, "bad" → badly (adverb), so "does worst" is not right.

> Note: "does the worst" = performs the poorest.

- This is a question about whether to speak louder.

- Or "more loudly"? Both possible, but louder is common.
- However, "louder" is adverbial form of "loud" — acceptable.
- But technically, "more loudly" is correct.
- But in practice, "louder" is often used.
- Since the base word is "loud", and we're modifying "speak", use more loudly.
