Step-by-step solution for: Vocabulary Review - ESL worksheet by luoliveira
Let’s go through each section step by step.

Section A: Write the opposites using prefixes
We need to add a prefix (like “un-”, “in-”, “dis-”, “im-”) to make the opposite meaning.
1. happy → unhappy
2. legal → illegal
3. able → unable
4. young → **not usually prefixed; but if forced, “non-young” — however, standard is no common prefix. Wait — actually, for this level, maybe they expect “old”? But instruction says “using prefixes”. Hmm… Let’s check: “young” doesn’t have a standard prefix opposite. Maybe skip? No — let’s think again. Actually, in some contexts, “non-young” is used, but it’s rare. Perhaps the worksheet expects us to use “un-” even if not perfect? Wait — better to stick with real words. Actually, looking at common school worksheets, sometimes they accept “non-young”, but I think for #4, it might be an error or they want “old” — but that’s not a prefix. Let me double-check all.
Actually, let’s do them properly:
Standard prefix opposites:
1. happy → unhappy
2. legal → illegal
3. able → unable
4. young → ??? → Actually, there’s no standard prefix opposite. But perhaps they mean “non-young”? Or maybe it’s a trick? Wait — let’s look ahead. Maybe for “young”, they expect “old” — but that’s not a prefix. Hmm. Let’s assume we must use prefixes only. So perhaps “non-young” — but that’s awkward. Alternatively, maybe the word is meant to be “youthful”? No. Let’s move on and come back.
Wait — actually, in many such worksheets, “young” is paired with “old” without prefix — but the instruction says “using prefixes”. So perhaps it’s a mistake? Or maybe they accept “non-young”. I’ll put “non-young” for now, but let’s verify others.
Better approach: Let’s list known prefix opposites:
5. believable → unbelievable
6. regular → irregular
7. honest → dishonest
8. appear → disappear
9. obey → disobey
10. like → dislike
11. attractive → unattractive
12. connect → disconnect
13. continue → discontinue
14. understand → misunderstand
15. tie → untie
16. button → unbutton
17. advantage → disadvantage
18. mature → immature
19. capable → incapable
20. organize → disorganize
21. dress → undress
22. fold → unfold
23. fortunate → unfortunate
24. fair → unfair
25. agree → disagree
26. approve → disapprove
27. polite → impolite
28. discreet → indiscreet
29. dependent → independent
30. pleasant → unpleasant
31. kind → unkind
32. real → unreal
33. healthy → unhealthy
34. cover → uncover
35. correct → incorrect
36. convenient → inconvenient
Now back to #4: young → ?
There is no standard prefix opposite. But in some educational materials, they might accept “non-young”, though it’s not ideal. However, upon second thought — perhaps the intended answer is “old”, but that violates the “prefix” rule. Since the instruction strictly says “using prefixes”, and “young” has no common prefix opposite, I suspect it might be an oversight. But to complete the task, I’ll use “non-young” as a last resort. However, let me check online or standard lists — actually, in many similar worksheets, “young” is not included because it doesn’t fit. But since it’s here, perhaps they expect “unyoung”? That’s not a word.
Wait — another idea: maybe “juvenile” vs “adult”, but again, not prefix. I think for accuracy, I should note that “young” doesn’t have a standard prefix opposite, but since this is a student worksheet, perhaps they made a mistake. To proceed, I’ll leave it as “non-young” for now, but I’m not satisfied.
Alternatively, let’s see if any other word is problematic. All others seem fine. For #4, I’ll put “non-young” reluctantly.
But wait — let’s think differently. Maybe “young” is meant to be “youthful”? No. Or perhaps it’s “aged”? Not prefix. I think I have to go with “non-young”.
Actually, upon re-examining, I recall that in some curricula, they teach “non-” as a prefix for negation, so “non-young” is acceptable in that context. So I’ll use that.
So:
4. young → non-young
But let’s confirm with reliable sources mentally — yes, “non-” can be used, though it’s less common. Okay.
---
Section B: Homonyms
Homonyms are words that sound the same but have different meanings and spellings.
1. their → there (or they’re, but usually “there” is the homonym taught first)
Actually, “their” homonyms are “there” and “they’re”. But typically in such exercises, they expect one. Let’s see the pattern.
Common pairs:
1. their → there
2. weight → wait
3. threw → through
4. knew → new
5. waist → waste
6. way → weigh
7. weak → week
8. wood → would
9. knight → night
10. know → no
11. cell → sell
12. cent → sent (or scent) — usually “sent”
13. forth → fourth
14. die → dye
15. flour → flower
16. right → write (or rite) — usually “write”
17. red → read (past tense)
18. sail → sale
19. see → sea
20. heal → heel
21. hear → here
22. some → sum
23. hole → whole
24. higher → hire
25. meat → meet
26. maid → made
27. in → inn
28. our → hour
29. knot → not
30. plane → plain
31. pear → pair (or pare) — usually “pair”
32. buy → by (or bye) — usually “by”
33. role → roll
34. sun → son
35. principle → principal
36. male → mail
Let me verify a few:
- “cent” homonym: “sent” (as in past tense of send) or “scent” (smell). Both are valid, but “sent” is more commonly paired in basic exercises. I’ll use “sent”.
- “higher” → “hire” (to employ)
- “male” → “mail” (letters)
All seem correct.

Section C: Corresponding noun or adjective form
The instruction says: “Write the corresponding noun or adjective form”
Looking at the words given, most are nouns, and we need to write the adjective form, or vice versa? Let’s see examples.
1. success → successful (adjective)
2. enthusiasm → enthusiastic
3. sarcasm → sarcastic
4. anger → angry
5. fortune → fortunate
6. humor → humorous
7. mercy → merciful
8. patience → patient
9. energy → energetic
10. dirt → dirty
11. absence → absent
12. beauty → beautiful
13. rain → rainy
14. fog → foggy
15. wave → wavy
16. affection → affectionate
17. mystery → mysterious
18. style → stylish
19. religion → religious
20. ignorance → ignorant
21. noise → noisy
22. truth → true
23. ambition → ambitious
24. power → powerful
25. depth → deep
26. high → height? Wait, no — the word given is “high”, which is adjective, so noun form is “height”
But let’s read the instruction: “corresponding noun or adjective form” — so if the given word is noun, give adjective; if adjective, give noun.
Check:
25. depth (noun) → deep (adjective)
26. high (adjective) → height (noun)
27. long (adjective) → length (noun)
28. cruel (adjective) → cruelty (noun)
29. generosity (noun) → generous (adjective)
30. dead (adjective) → death (noun)
31. free (adjective) → freedom (noun)
32. confuse (verb?) — wait, “confuse” is verb, but the list has nouns/adjectives. Problem.
Look at 32: confuse — that’s a verb. But the section says “noun or adjective form”. Perhaps it’s a mistake? Or maybe they mean the adjective form of “confuse” is “confused”, but that’s participle.
This is tricky. Let’s analyze the pattern.
Most items are either noun → adjective or adjective → noun.
For verbs, it might be different. But “confuse” is listed, so perhaps they want the adjective “confused” or “confusing”. Typically, “confused” is the adjective form.
Similarly, 33. indifferent — that’s already an adjective, so noun form is “indifference”
34. regular — adjective, noun is “regularity” or “regular” as noun? Usually “regularity”
35. silent — adjective, noun is “silence”
36. hateful — adjective, noun is “hatred”
But let’s go systematically.
Given words and what to convert to:
If the word is a noun, write adjective.
If adjective, write noun.
But some are verbs? Like “confuse”.
Perhaps for verbs, they want the adjective form.
Let’s list:
25. depth (noun) → deep (adj)
26. high (adj) → height (noun)
27. long (adj) → length (noun)
28. cruel (adj) → cruelty (noun)
29. generosity (noun) → generous (adj)
30. dead (adj) → death (noun)
31. free (adj) → freedom (noun)
32. confuse (verb) → confused (adj) [commonly accepted]
33. indifferent (adj) → indifference (noun)
34. regular (adj) → regularity (noun)
35. silent (adj) → silence (noun)
36. hateful (adj) → hatred (noun)
For 32, “confuse” is a verb, but in such contexts, they often expect “confused” as the adjective form.
Similarly, all others seem consistent.
Now, back to Section A #4: young → I think I should use “non-young” as per prefix rule, even if uncommon.
But let me double-check if there’s a better way. Upon second thought, in many standardized tests, “young” is not paired with a prefix opposite, so perhaps it’s an error. But to complete, I’ll keep “non-young”.
Alternatively, maybe they expect “old”, but that’s not a prefix. I think for consistency, I’ll use “non-young”.
Final decision: proceed with “non-young”.
