## 🧠 What is a Prefix?
A prefix is a group of letters added to the beginning of a word to change its meaning. Common prefixes include: *un-, dis-, mis-, re-, pre-, im-, in-, ab-, en-, etc.*

---

# Part A: Circle the word with a prefix.

We’ll go one by one and identify which word has a prefix.

---

1) sail — proud — disconnect — golden


disconnect = “dis-” + “connect” → “dis-” is a prefix meaning “not” or “opposite of”
Circle: disconnect

---

2) abnormal — market — neatly — burst


abnormal = “ab-” + “normal” → “ab-” means “away from” or “not”
Circle: abnormal

---

3) dentist — kindness — gentle — improper


improper = “im-” + “proper” → “im-” is a variation of “in-”, meaning “not”
Circle: improper

---

4) relax — extend — careless — bright


careless = “care” + “-less” → Wait! “-less” is a suffix, not a prefix.
But look again: “relax” = “re-” + “lax” → “re-” means “again” → Prefix!
“extend” = “ex-” + “tend” → “ex-” means “out” → Also a prefix!
Wait — the instruction says “circle the word with a prefix” — implying one per row. But multiple words may have prefixes!

Let’s check all:

- relax → prefix “re-”
- extend → prefix “ex-”
- careless → suffix “-less” (not prefix)
- bright → no prefix

So both “relax” and “extend” have prefixes. But since it says “the word” (singular), we should pick one. Usually, worksheets expect the most obvious or first correct answer.

Circle: relax (or extend — both are correct, but let’s go with relax as it’s first)

> 💡 Note: If your teacher allows multiple, you could circle both. But for standard answers, we’ll pick relax.

---

5) interact — glow — fear — careful


interact = “inter-” + “act” → “inter-” means “between” → prefix
Circle: interact

---

## Final Answers for Part A:
1) disconnect
2) abnormal
3) improper
4) relax (or extend — both valid, but relax is more commonly taught first)
5) interact

---

# Part B: Underline the word with a prefix, in each sentence.

We underline the entire word that contains a prefix.

---

1) Playing with sharp objects is unsafe.


unsafe = “un-” + “safe” → “un-” is a prefix meaning “not”
Underline: unsafe

---

2) Issac never misbehaves.


misbehaves = “mis-” + “behaves” → “mis-” means “wrongly”
Underline: misbehaves

---

3) Rebecca enlarged the picture.


enlarged = “en-” + “large” + “-ed” → “en-” is a prefix meaning “to make”
Underline: enlarged

---

4) The magician made the rabbit disappear.


disappear = “dis-” + “appear” → “dis-” means “away” or “reverse”
Underline: disappear

---

5) John repainted his living room.


repainted = “re-” + “painted” → “re-” means “again”
Underline: repainted

---

## Final Answers for Part B:
1) unsafe
2) misbehaves
3) enlarged
4) disappear
5) repainted

---
