Educational worksheet for students to practice prefixes by filling in the blanks with correct prefixes from a provided bank.

Let's solve this worksheet step by step. The goal is to fill in the correct prefix from the Bank of Prefixes to complete each word.

---

🔤 Bank of Prefixes:

- de-
- ex-
- im-
- mis-
- pre-
- un-
- dis-
- il-
- in-
- non-
- re-
- with-

We'll go through each word and determine which prefix makes sense based on meaning and common usage.

✔ Solutions:

| Word | Correct Prefix | Full Word | Explanation |
|------|----------------|-----------|-------------|
| ___ fix | re- | refix | To fix again; "re-" means again. |
| ___ sense | dis- or mis- | dis-sense (rare), mis-sense | "Mis-sense" = incorrect understanding. "Dis-sense" is not common, but "dis-" can mean lack of. More likely: mis- for incorrect sense. |
| ___ happy | un- | unhappy | Common word; "un-" means not. |
| ___ mind | dis- | dismind? No. Wait — dis- → dis-mind is not a word. But de-? No. Actually, "mind" is often used in "disregard", but here we have "dis-mind" — not valid. Wait — maybe it's "unmind"? Not common. Actually, "pre-mind"? No. Let’s think: "mis-?" → misunderstand? No. Wait — perhaps it's "dis- as in disdain? But not dis-mind. Hmm. Maybe "pre-mind"? No. Wait — "dis- is used in "disrespect", but not "dis-mind". Perhaps it's "de-? de-mind? No. Wait — actually, "dis- is used in "disagree", but not "dis-mind". Is there a word like "dis-mind"? Not really. Wait — could it be "non-mind"? Not common. Or "il-? il-mind? No. Maybe "in-? in-mind? No. This one might be tricky. Let’s skip and come back. |

Wait — let's check if there's a typo or if we're missing something.

Actually, "dis- is used in "disregard", but "dis-mind" isn't standard. However, "dis- can mean “not” or “lack of,” so "dis-mind" could be interpreted as “lacking mind,” but it's not a real word.

Wait — maybe it's "pre-mind"? No. Or "re-mind"? Yes! "remind" is a real word!

So:
✔ ___ mind → re- → remind (to cause someone to remember)

That makes sense!

So:
| ___ mind | re- | remind | "re-" = again, back; to bring back to mind |

Let’s continue:

| ___ pert | im- or in- | impertinent or in-pertinent? Wait — "impertinent" = rude, disrespectful. But "pert" means bold, so "im- is used: impertinent → im- |
| --- | --- | --- | --- |
| ___ respect | dis- | disrespect | "dis-" means lack of; disrespect = lack of respect |

| ___ equal | in- or un- or non- | unequal, inequal, non-equal | All are valid. But "in- is most common: inequal (though "unequal" is more common). Both in- and un- work. |
| --- | --- | --- | --- |
| ___ legal | il- or in- | illegal or illegal → il- is correct: illegal (from Latin) |
| ___ fiction | pre- | pre-fab? No. pre-fiction? Not common. Wait — "fiction" → "non-fiction" → non- |
| --- | --- | --- | --- |
| ___ prove | dis- | disprove | "dis-" means not; to show something is false |
| ___ frost | de- | defrost | "de-" means remove; to remove frost |
| ___ ceed | pro-? Not in bank. Wait — prefixes in bank: re- → receed? No. pre- → precede? Yes! pre- → precede (to go before) |
| --- | --- | --- | --- |
| ___ lucky | un- | unlucky | "un-" means not |
| ___ lead | mis- | mislead | "mis-" means wrong; to lead wrongly |
| ___ fat | ex- | ex-fat? No. "ex-" means former: ex-husband, but not ex-fat. Wait — "overweight"? Not helpful. Wait — "fat" → "de-fat"? Like defatting? de- → defat (remove fat) — yes! So de-fat? But "defat" is not common. But "de-fat" is used in technical contexts. Alternatively, "non-fat"? Yes! non-fat is common. So non- → non-fat |
| --- | --- | --- | --- |
| ___ fair | un- | unfair | "un-" means not |
| ___ gust | pre- | pregust? No. "gust" → "outgust"? No. Wait — "with- → withgust? No. Wait — "disgust" → dis-! Yes! disgust = strong dislike |
| --- | --- | --- | --- |
| ___ hold | with- | withhold | "with-" means hold back |
| ___ place | re- | replace | "re-" means again; to put back in place |
| ___ usual | un- or in- | unusual or inusual? Both are valid, but unusual is more common. "in- is also used: inusual? No — "in- + usual = "inusual"? Actually, "in- is not used in "unusual" — it's "un-". So un- → unusual |
| --- | --- | --- | --- |
| ___ portant | im- | important | "im-" is used in important (from Latin "importans") — im- |
| ___ draw | re- | redraw | "re-" means again; to draw again |
| ___ logical | il- or in- | illogical or unlogical? "illogical" uses il- (common for words starting with "l") → il- |
| ___ retrieve | re- | retrieve → already has "re-"? Wait — no. "retrieve" starts with "re-" → so re- is correct. But the blank is before "trieve"? That would be "re-trieve" → retrieve → so re- |
| --- | --- | --- | --- |
| ___ visible | in- or im- | invisible → in- is correct. "in-" means not; invisible = cannot be seen |
| ___ play | re- | replay | "re-" means again; to play again |
| ___ cellent | ex- | excellent | "ex-" means out of, beyond; excellent = beyond ordinary |
| ___ view | re- | review | "re-" means again; to look over again |
| ___ code | de- | decode | "de-" means reverse; to decode = to break a code |
| ___ flex | in- or im- | inflex? No. "flexible" → inflexible → in- or im-? Actually, "inflexible" uses in- (not im-) → in- |

📝 Notes:

- Some words allow multiple prefixes (e.g., equal: *unequal*, *inequal*, *non-equal*).
- "Sense" → mis-sense is rare; "dis-sense" is not standard. But "mis- is best choice.
- "Fat" → non-fat is most common; de-fat is technical.
- "Cellent" → excellent → ex-
- "Flex" → inflexible → in- (not im-)

re- fix mis- sense un- happy
re- mind im- pert dis- respect
in- equal il- legal non- fiction
dis- prove de- frost pre- ceed
un- lucky mis- lead non- fat
un- fair dis- gust with- hold
re- place un- usual im- portant
re- draw il- logical re- trieve
in- visible re- play ex- cellent
re- view de- code in- flex
```

> Note: Some answers may vary slightly (e.g., in- vs un- for *equal*), but these are the most common and accepted forms.
