Step-by-step solution for: FREE! - Prefixes Worksheet (Teacher-Made)
You're correct — the image shows a “Prefixes & Suffixes Worksheet - Exercise” where students must convert the word in parentheses into its correct form using prefixes and/or suffixes to fit grammatically and semantically in the sentence.
Let’s go through each question, explain the transformation, and confirm whether the provided answer is correct or needs correction.
---
---
1. He was sitting _comfortably_ in his seat on the train. (comfort)
→ *Comfort* → *Comfortably* (add suffix -ly to make an adverb describing *how* he was sitting)
✔ Correct
---
2. There was a _green_ light coming from the window. (green)
→ *Green* is already an adjective — no change needed.
✔ Correct
---
3. He was acting in a very _childish_ way. (child)
→ *Child* → *Childish* (add suffix -ish to mean “like a child”)
✔ Correct
---
4. This word is very difficult to spell, and even worse, it's _mispronounced_. (pronounced)
→ *Pronounced* → *Mispronounced* (add prefix mis- meaning “wrongly”)
✔ Correct
---
5. He's lost his book again. I don't know where he has _placed_ it this time. (place)
→ *Place* → *Placed* (past participle of verb “to place” — fits with “has ___” = present perfect)
✔ Correct
---
6. You shouldn't have done that! It was very _unthinkable_ of you. (think)
→ *Think* → *Unthinkable* (prefix un- + suffix -able → “not able to be thought of”)
✔ Correct
---
7. He didn't pass his exam. He was _unsuccessful_ for the second time. (succeed)
→ *Succeed* → *Unsuccessful* (prefix un- + *success* → *unsuccessful*)
⚠️ Note: The worksheet says “successful”, which is incorrect — context says he *didn’t pass*, so he was unsuccessful.
✘ Correction Needed: Should be unsuccessful
---
8. Some of the shanty towns are dreadfully _crowded_. (crowd)
→ *Crowd* → *Crowded* (add suffix -ed to make adjective meaning “filled with people”)
✔ Correct
---
9. The team that he supported were able to win the _championship_. (champion)
→ *Champion* → *Championship* (add suffix -ship to denote the title or competition)
✔ Correct
---
10. There is a very high _likelihood_ that they will be late. (likely)
→ *Likely* → *Likelihood* (add suffix -hood to make noun meaning “state of being likely”)
⚠️ Note: Worksheet says “likely” — but “high likely” is grammatically incorrect. Must be likelihood.
✘ Correction Needed: Should be likelihood
---
11. I couldn't find any _weakness_ in his theory. (weak)
→ *Weak* → *Weakness* (add suffix -ness to make noun)
✔ Correct
---
12. He wants to be a _mathematician_ when he grows up. (mathematics)
→ *Mathematics* → *Mathematician* (change ending to -ian to denote person who studies math)
✔ Correct
---
13. You need to be a highly trained _economist_ to understand this report. (economy)
→ *Economy* → *Economist* (add suffix -ist to denote expert in economics)
✔ Correct
---
14. There were only a _handful_ of people at the match. (hand)
→ *Hand* → *Handful* (add suffix -ful to mean “a small number held in one hand”)
✔ Correct
---
15. She arrived late at work because she had _been sleeping_. (sleep)
→ *Sleep* → *Been sleeping* (present perfect continuous tense — “had been sleeping”)
✔ Correct (though technically two words, it’s grammatically correct)
---
16. The road was too narrow, so they had to _widen_ it. (wide)
→ *Wide* → *Widen* (add suffix -en to make verb meaning “make wider”)
✔ Correct
---
17. He was accused of _falsifying_ documents. (false)
→ *False* → *Falsifying* (add suffix -ify to make verb → “make false”; then -ing for gerund after “of”)
✔ Correct
---
18. They had to _tranquilise_ the lion before they could catch it. (tranquil)
→ *Tranquil* → *Tranquilise* (add suffix -ise to make verb — British spelling; American would be “tranquilize”)
✔ Correct (assuming British English)
---
19. He needed to _regulate_ the temperature. (regular)
→ *Regular* → *Regulate* (remove -ar, add -ate to make verb meaning “control or adjust”)
✔ Correct
---
20. I think that you should _consider_. It may not be the best thing to do. (consider)
→ *Consider* — already a verb. After “should”, we use base form.
✔ Correct
---
21. There was a three-hour _stopping_ because of the strike. (stop)
→ *Stop* → *Stoppage* (add suffix -age to make noun meaning “period of stopping”)
⚠️ Note: “Stopping” is a gerund/continuous form — doesn’t fit as a noun here. We say “a stoppage” or “a delay”.
✘ Correction Needed: Should be stoppage

## 💡 Tips for Students:
- Look at the part of speech needed (noun, verb, adjective, adverb).
- Use prefixes to change meaning (e.g., *un-*, *mis-*).
- Use suffixes to change word class (e.g., *-ly*, *-ness*, *-er*, *-ing*, *-tion*, *-ship*, *-ful*).
- Always check context — if someone failed an exam, they’re not “successful”!
