Fun grammar activity where students hunt for words transformed by the prefix 'un-' within a letter grid.

Let’s solve this step by step.

We are looking for 16 words that can be made by adding the prefix “un-” to each word in the list. That means we take each base word and add “un” at the beginning — like turning “happy” into “unhappy”.

Here’s the list of base words:

able
employed
acceptable
expected
afraid
finished
answered
furnished
believable
happy
clear
healthy
comfortable
kind
complicated
used

Now, let’s make the “un-” version of each:

1. able → unable
2. employed → unemployed
3. acceptable → unacceptable
4. expected → unexpected
5. afraid → unafraid
6. finished → unfinished
7. answered → unanswered
8. furnished → unfurnished
9. believable → unbelievable
10. happy → unhappy
11. clear → unclear
12. healthy → unhealthy
13. comfortable → uncomfortable
14. kind → unkind
15. complicated → uncomplicated
16. used → unused

Now, we need to find these 16 “un-” words hidden in the word search grid. They can be going up, down, left, right, or diagonally — but since it’s a standard word search, usually they’re horizontal, vertical, or diagonal (forward only).

Let’s go one by one and locate them in the grid.

But wait — actually, you don’t need me to point out where they are in the grid unless asked. The task is just to *find* their “un-” forms — meaning, write down what they become with “un-” added.

Looking back at the instructions:
> Below are 16 words. Find their PREFIX ‘UN-’ forms.

So the actual homework task is simply to transform each word by adding “un-” at the front.

That’s it! No need to hunt through the grid unless you’re doing the full puzzle — but the question here is asking you to produce the “un-” versions.

Let me double-check each transformation to make sure they’re all correct English words:

✔ unable – yes
✔ unemployed – yes
✔ unacceptable – yes
✔ unexpected – yes
✔ unafraid – yes (less common, but valid)
✔ unfinished – yes
✔ unanswered – yes
✔ unfurnished – yes
✔ unbelievable – yes
✔ unhappy – yes
✔ unclear – yes
✔ unhealthy – yes
✔ uncomfortable – yes
✔ unkind – yes
✔ uncomplicated – yes
✔ unused – yes

All 16 are real words formed correctly with “un-”.

Final Answer:
unable, unemployed, unacceptable, unexpected, unafraid, unfinished, unanswered, unfurnished, unbelievable, unhappy, unclear, unhealthy, uncomfortable, unkind, uncomplicated, unused
