Suffixes Worksheets - Free Printable

Let's solve this Suffixes Worksheet step by step.

We are given a word bank with these suffixes:

- ness
- ment
- ful
- s

Our task is to add the correct suffix to each root word to form a meaningful word.

Step-by-step Analysis:

1. Care
→ "Care" + ness = Carenness? ✘ (Not a real word)
→ "Care" + ful = Careful ✔ (Yes, means full of care)
→ "Care" + s = Cares ✔ (plural, but we need a suffix that forms a meaningful word)
But the instruction says to pick from the word bank. Let’s see which one fits best.

Actually, “care” + ful = careful – this is correct and common.

✔️ Answer: ful

2. Hard
→ "Hard" + ness = Hardness ✔ (means the quality of being hard)
→ "Hard" + ful = Hardful? ✘ (not a word)
→ "Hard" + s = Hards? ✘ (not commonly used)
→ "Hard" + ment = Hardment? ✘ (not a word)

✔️ Answer: ness

3. Treat
→ "Treat" + ment = Treatment ✔ (a common word)
→ "Treat" + s = Treats ✔ (plural)
→ "Treat" + ness = Treatness? ✘
→ "Treat" + ful = Treatful? ✘

But “treatment” is more meaningful in context. Also, “treats” is valid, but “treatment” uses the suffix ment, which is in the word bank.

✔️ Answer: ment

4. Soft
→ "Soft" + ness = Softness ✔ (the quality of being soft)
→ "Soft" + ful = Softful? ✘
→ "Soft" + s = Softs? ✘
→ "Soft" + ment = Softment? ✘

✔️ Answer: ness

5. Amaze
→ "Amaze" + ment = Amazement ✔ (a feeling of wonder)
→ "Amaze" + s = Amazes ✔ (third person singular)
→ "Amaze" + ness = Amazenness? ✘
→ "Amaze" + ful = Amazeful? ✘

“Amazement” is a strong, correct word using ment.

✔️ Answer: ment

6. Dry
→ "Dry" + ness = Dryness ✔ (the state of being dry)
→ "Dry" + ful = Dryful? ✘
→ "Dry" + s = Drys? ✘ (rarely used)
→ "Dry" + ment = Dryment? ✘

✔️ Answer: ness

7. Toy
→ "Toy" + s = Toys ✔ (plural)
→ "Toy" + ness = Toyness? ✘
→ "Toy" + ment = Toyment? ✘
→ "Toy" + ful = Toyful? ✘

Only s makes sense here.

✔️ Answer: s

8. Move
→ "Move" + ment = Momentum? Wait — no!
Actually, "Move" + ment = Movement ✔ (yes, movement)
→ "Move" + s = Moves ✔ (plural or third person)
→ "Move" + ness = Moveness? ✘
→ "Move" + ful = Moveful? ✘

“Movement” is a standard word. So use ment.

✔️ Answer: ment

9. Sad
→ "Sad" + ness = Sadness ✔ (the feeling of being sad)
→ "Sad" + ful = Sadful? ✘
→ "Sad" + s = Sads? ✘
→ "Sad" + ment = Sadment? ✘

✔️ Answer: ness

10. Hope
→ "Hope" + s = Hopes ✔ (plural or third person)
→ "Hope" + ment = Hopement? ✘
→ "Hope" + ness = Hopeness? ✘
→ "Hope" + ful = Hopeful ✔ (means full of hope)

Now we have two options: s and ful.

But hopeful is a very common word. “Hopes” is also valid.

However, the suffix ful turns “hope” into an adjective meaning “full of hope.”

Since both are possible, but hopeful is more likely intended here as it uses a meaningful suffix from the bank.

✔️ Answer: ful

- ful: Makes adjectives meaning "full of" (e.g., careful, hopeful)
- s: Plural form (e.g., toys, hopes)
