Show Answer Key & Explanations Step-by-step solution for: Dis, Un and Mis Prefix Worksheets (teacher made) - Twinkl
Let’s go through each sentence one by one and pick the correct prefix: im, dis, or un.

---

1. It seems ___possible to make Tom laugh.

We’re looking for a word that means “not possible.”
The correct prefix here is imimpossible.
(“Dispossible” and “unpossible” are not real words.)

So, answer: im

---

2. These shoes are ___comfortable.

We want to say the shoes are *not* comfortable.
The correct prefix is ununcomfortable.
(“Discomfortable” isn’t used — we say “uncomfortable.” “Imcomfortable” doesn’t exist.)

So, answer: un

---

3. Your closet is ___tidy!

We mean the closet is *not tidy*.
Correct prefix: ununtidy.
(“Distidy” and “imtidy” aren’t real words.)

So, answer: un

Wait — let me double-check! Actually, sometimes people might think of “disorganized,” but the word given is “tidy.” The opposite of “tidy” is “untidy.” Yes, un is correct.

But hold on — look at the picture: the closet is messy. And the sentence says “Your closet is ___tidy!” — so it’s saying it’s NOT tidy. Definitely untidy.

Confirmed: un

---

4. It is ___polite to use loud voice in the classroom.

We mean it’s *not polite*.
Correct prefix: imimpolite.
(“Dispolite” and “unpolite” are not standard English.)

So, answer: im

---

5. You always ___agree with me!

We mean you do *not agree* — you disagree.
Correct prefix: disdisagree.
(“Unagree” is sometimes heard but not correct; “imagree” doesn’t exist.)

So, answer: dis

---

Now let’s list all answers:

1. im
2. un
3. un
4. im
5. dis

Wait — let me check #3 again. Is there any chance it’s “dis”? No — “distidy” is not a word. “Untidy” is correct.

Also, for #2: “uncomfortable” is correct. Not “discomfortable” — that’s not how we say it.

All good.

Final Answer:
1. im
2. un
3. un
4. im
5. dis
