Educational worksheet for practicing prefixes and suffixes with a word-building exercise.

Let's solve this worksheet step by step. The goal is to fill in the correct prefixes and suffixes from the provided banks to form real, meaningful words.

---

Banks:

Prefixes:
- dis-, im-, mis-, un-, il-, in-, re-

Suffixes:
- -able, -ance, -ion, -ment, -al, -ful, -ly, -y

---

We will go through each root word and determine appropriate prefix and/or suffix combinations.

---

Left Column (Prefix - Root Word - Suffix)

1. ___place
→ "displace" (to move or remove from a place)
→ dis-place ✔
→ Also possible: re-place (to put back), mis-place (to put in wrong place)
→ So: dis-place, re-place, mis-place

2. ___law
→ "illegal" (not legal), "unlawful"
→ But here it’s ___law___, so we need prefix + law + suffix
→ "il-law" → "illegal" → il-law-ful? No, “illegal” doesn’t have a suffix.
→ Wait — let's think:
- "illegal" = il- + legal → but no suffix
- "unlawful" = un- + law + -ful → Yes!
→ So: un-law-ful ✔
→ Also: dis-law? No. in-law? Not a word.
→ Best: un-law-ful

3. ___legal
→ "illegal" = il- + legal → but no suffix
→ Can we add suffix? "legality"? That would be legal + -ity, but not in bank.
→ Bank has: -able, -ance, -ion, -ment, -al, -ful, -ly, -y
→ "legal" → "legally" = legal + -ly → il-legal-ly? That’s “illegally”, but that’s il- + legal + -ly
→ So: il-legal-ly ✔
→ Also: in-legal? No. un-legal? "Unlegal" is rare; "illegal" is standard.
→ So best: il-legal-ly

4. ___mature
→ "immature" = im- + mature → im-mature ✔
→ Also: "premature"? But "pre-" not in bank.
→ "unmature"? Not common.
→ So: im-mature

5. ___taken
→ "untaken"? Rare. "mistaken"? Yes! mis-taken ✔
→ "dis-taken"? No. "re-taken"? Yes! re-taken ✔
→ So: mis-taken, re-taken

6. ___humane
→ "inhumane" = in- + humane → in-humane ✔
→ "un-humane"? Possible, but "inhumane" is standard.
→ So: in-humane

7. ___assign
→ "reassign" = re- + assign → re-assign ✔
→ "misassign"? Less common, but possible.
→ "disassign"? No.
→ So: re-assign, possibly mis-assign

8. ___health
→ "unhealthy" = un- + health + -y → un-health-y ✔
→ "healthful"? Yes! health + -ful → but no prefix → __health-ful → can't add prefix
→ But the format is prefix-root-suffix, so we need both.
→ "un-health-ful"? "Unhealthful" exists (rare), but better to use un-health-y
→ Or in-health-ful? No.
→ So best: un-health-y

9. ___account
→ "accountable" = account + -able → need prefix?
→ "dis-account"? No. "mis-account"? No.
→ "re-account"? "Recount"? Yes! But that's re-count, not account.
→ "account" → "accountable" → ac-count-able → no prefix
→ But we must use prefix?
→ "disaccount"? No.
→ "in-account"? No.
→ "unaccountable"? Yes! un-account-able ✔
→ So: un-account-able

10. ___live
→ "unlively"? "Lively" is live + -ly, but "unlively"? No.
→ "alive"? But no prefix for "alive" → al-ive? No.
→ "dis-live"? No.
→ "re-live"? Yes! re-live ✔
→ "mis-live"? No.
→ "un-live"? No.
→ So: re-live

---

Right Column (Prefix - Root Word - Suffix)

1. ___enforce
→ "enforcement" = enforce + -ment → enforce-ment → no prefix needed
→ But we need prefix?
→ "dis-enforce"? "Disenforce"? Not common.
→ "re-enforce"? Yes! re-enforce ✔
→ "mis-enforce"? Possible.
→ So: re-enforce, mis-enforce

2. ___arrange
→ "rearrange" = re- + arrange → re-arrange ✔
→ "misarrange"? Possible.
→ "disarrange"? "Disarray", but not "disarrange".
→ So: re-arrange, mis-arrange

3. ___develop
→ "development" = develop + -ment → devel-op-ment → no prefix
→ But we can add prefix?
→ "underdeveloped"? But "under-" not in bank.
→ "undeveloped"? "Un-develop-ed"? But "-ed" not in suffix bank.
→ "re-develop"? Yes! re-develop ✔
→ "mis-develop"? "Misdevelop"? Yes, possible.
→ So: re-develop, mis-develop

4. ___taste
→ "tasteful" = taste + -ful → taste-ful → no prefix
→ But we can use prefix?
→ "dis-taste"? "Distaste" = dis- + taste → dis-taste ✔
→ "mis-taste"? No.
→ "un-taste"? "Untasty"? No.
→ So: dis-taste

5. ___finite
→ "infinite" = in- + finite → in-finite ✔
→ "unfinite"? No.
→ "disfinite"? No.
→ So: in-finite

6. ___act
→ "action" = act + -ion → act-ion → no prefix
→ But we need prefix?
→ "react" = re- + act → re-act ✔
→ "misact"? "Misconduct"? Not "misact".
→ "disact"? No.
→ So: re-act

7. ___help
→ "helpful" = help + -ful → help-ful → no prefix
→ "unhelpful"? Yes! un-help-ful ✔
→ "dis-help"? No.
→ So: un-help-ful

8. ___know
→ "knowledge"? "Know + -ledge"? Not in bank.
→ "knowing"? "Know + -ing"? Not in bank.
→ "unknowing"? un-know-ing? But "-ing" not in suffix bank.
→ "knowable"? know + -able → know-able → no prefix
→ "unknowable"? un-know-able ✔
→ So: un-know-able

9. ___appear
→ "appearance" = appear + -ance → appear-ance → no prefix
→ "reappear"? re-appear ✔
→ "disappear"? dis-appear ✔
→ "misappear"? No.
→ So: re-appear, dis-appear

10. ___avoid
→ "avoidable" = avoid + -able → avoid-able → no prefix
→ "unavoidable"? un-avoid-able ✔
→ "disavoid"? No.
→ So: un-avoid-able
