Let's solve this Grade 3 English worksheet on prefixes step by step.

🔤 Objective:

Use the prefixes from the Word Box to complete each word. The goal is to form real, meaningful words using the given root words and choosing the correct prefix.

✔ Word Box (Prefixes):

- un-
- mis-
- im-
- re-
- uni-
- ex-
- de-
- pre-
- in-
- dis-
- non-
- pro-

We will go through each blank and determine which prefix makes sense.

📝 Column 1:

1. ______ chief
→ "un-" → unchief? No.
→ "ex-" → ex-chief → Yes! Meaning: former chief.
✔ ex-chief

2. ______ trust

✔ dis-trust

→ "dis-" → dispair? No.
→ "uni-" → unipair? No.
→ "in-" → inpair? No.
→ "non-" → non-pair? Possible but rare.
Wait — "re-" → repair? But that’s not “pair”.
Actually, "mis-" → mispair? Not standard.
But wait: "dis-" → dispair? No.
Let's think: "un-" → unpair? Not a word.
Hmm... Maybe it's "re-" → repair? But root is "pair", so repair = re + pair → ✔ re-pair

✔ re-pair

6. ______ vise
→ "pre-" → pre-vise? No.
→ "pro-" → pro-vise? No.
→ "dis-" → dis-vise? No.
→ "ad-"? Not in box.
Wait: "adviser" → advise → disadvise? But here it's "vise".
Actually, "advice" → advise, so "disadvise"? But we have "vise".
Wait — "re-" → re-vise → Yes! revise → to change or edit again.
✔ re-vise

7. ______ ject

Actually, "im-" + "perfect" → imperfect → yes!
So: im- + perfect → but here it's written as ______ fect → so likely im-perfect → but only "fect" is shown.
But "im-" + "perfect" → "imperfect" → so prefix is im-
✔ im-fect → actually, imperfect → so im-

✔ im-fect → imperfect
