Let’s go step by step to solve this prefix worksheet.
---
Part One: Write which word is being described.
We need to think of words that match the description, using common prefixes like *pre-*, *re-*, *un-*, *dis-*.
1.
To heat before → “Pre” means before. So, “preheat” = heat before (like preheating an oven).
✔ Answer:
preheat
2.
To not like → “Dis” can mean opposite or not. “Dislike” = not like.
✔ Answer:
dislike
3.
To do the opposite of tie → “Untie” = to undo a tie. “Un-” means reverse.
✔ Answer:
untie
4.
To write again → “Re” means again. “Rewrite” = write again.
✔ Answer:
rewrite
5.
To pay before → “Prepay” = pay before (like prepaying for something).
✔ Answer:
prepay
6.
To do the opposite of pack → “Unpack” = take things out of a pack/box.
✔ Answer:
unpack
7.
To use again → “Reuse” = use again.
✔ Answer:
reuse
---
Part Two: Add a prefix (pre-, re-, un-, dis-) to the base word to create a new word.
We’ll pick the correct prefix for each base word so it makes sense.
8. ___play → “Replay” = play again (common in games/videos)
✔ re
9. ___honest → “Dishonest” = not honest
✔ dis
10. ___do → “Undo” = reverse doing something
✔ un
11. ___known → “Unknown” = not known
✔ un
12. ___heat → “Preheat” = heat before (as in Part One)
✔ pre
13. ___pay → “Prepay” = pay before
✔ pre
14. ___fund → “Refund” = give money back (re- = again/back)
✔ re
15. ___read → “Reread” = read again
✔ re
16. ___true → “Untrue” = not true
✔ un
17. ___use → “Reuse” = use again
✔ re
18. ___obey → “Disobey” = not obey
✔ dis
19. ___school → “Preschool” = school before regular school (for young kids)
✔ pre
20. ___charge → “Recharge” = charge again (like a battery)
✔ re
21. ___agree → “Disagree” = not agree
✔ dis
