Grade 3 Grammar Topic 21: Prefix and Suffix Worksheets - Lets ... - Free Printable

Let’s solve each sentence by adding the correct prefix or suffix from the given table to the root word in brackets.

---

First, understand the table:

The prefixes and suffixes are grouped as follows:

Prefixes (beginning of word):
- dis-, un-, semi-, anti-
- in-, fore-, mid-, inter-

Suffixes (end of word):
- -ward, -ed, -ly, -ish
- -hood, -er, -tion, -hood (repeated)

---

Now, let’s go one by one:

---

1. I look __________ [for] to going to the amusement park.

We need a word that means “eagerly anticipate” — the phrase is “look forward to”.

✔ Answer: forward

> *“Forward” is formed by adding the suffix “-ward” to “for”. “For” + “-ward” = “forward”.*

---

2. My favorite iPad cover is __________ [purple].

We need an adjective meaning “somewhat purple” or “having a purple color”.

✔ Answer: purplish

> *Add the suffix “-ish” to “purple” → “purplish” (meaning somewhat purple).*

---

3. Please draw a __________ [circle].

We need a noun meaning “a circular shape” — but “circle” is already a noun. However, if we add “-er”, we get “circler” — which doesn’t make sense.

Wait — maybe it’s asking for a verb form? But the sentence says “draw a ________”, so we need a noun.

Actually, “circle” is fine as is — but we must add a prefix/suffix from the list.

Let’s think: what if we add “-er”? “Circler” isn’t standard.

What if we add “-ish”? “Circleish” — not common.

Wait — perhaps it’s a trick? Or maybe we’re supposed to use “semi-”?

→ “semicircle” — YES! That’s a real word, and “semi-” is in the prefix list.

✔ Answer: semicircle

> *“Semi-” + “circle” = “semicircle” — a half-circle. Common shape to draw.*

---

4. You can go __________ [month] after you get your report card.

We need an adverb meaning “after one month” — “monthly” is an adjective, not adverb.

But “month” + “-ly” = “monthly” — which can be used adverbially in context like “you can go monthly” — meaning once per month.

Alternatively, “month” + “-ward” = “monthward” — not a real word.

“Month” + “-er” = “monther” — nonsense.

So best fit: monthly

✔ Answer: monthly

> *“Monthly” = happening every month. Fits context: “You can go monthly after you get your report card.”*

---

5. The __________ [brother] of knights was based on loyalty.

We need a noun meaning “group or association of brothers” — especially in context of knights.

“Brother” + “-hood” = “brotherhood” — perfect!

✔ Answer: brotherhood

> *“Brotherhood” = a group of people united by a common interest or purpose — fits knights based on loyalty.*

---

6. She acted __________ [mother] when she helped her little sister.

We need an adverb meaning “in a motherly way”.

“Mother” + “-ly” = “motherly”

✔ Answer: motherly

> *“Motherly” = behaving with the care or tenderness of a mother. Perfect fit.*

---

## ✔ Final Answers:

1. forward
2. purplish
3. semicircle
4. monthly
5. brotherhood
6. motherly
