Interactive worksheet for learning prefixes and suffixes with matching and word-building activities.

Let's solve the "Prefixes and Suffixes" worksheet step by step. The image contains two parts: A and B.

---

Part A: Match the corresponding prefix/suffix

We are given a list of prefixes on the left and suffixes on the right. We need to match them correctly.

#### Prefixes (left):
- dis
- less
- im
- ness
- re

#### Suffixes (right):
- oct
- weak
- respect
- perfect
- use

Wait — this seems confusing because some items are not typical prefixes or suffixes. Let’s analyze:

Actually, looking closely:

The words on the right are likely base words, not suffixes. But the instruction says "Match the corresponding prefix/suffix".

But here's the issue: "oct", "weak", "respect", "perfect", "use" — these are not suffixes. For example:
- "oct" is part of "octopus", but not a suffix.
- "weak" is a word.
- "respect" is a word.
- "perfect" is a word.
- "use" is a word.

So perhaps there’s a typo in the interpretation. Let’s reconsider.

Wait — maybe the right column is meant to be base words, and we're supposed to match prefixes from the left with base words from the right?

But the instructions say: *"Match the corresponding prefix/suffix."*

Alternatively, it might be that the right side has suffixes, but they’re written as full words? That doesn't make sense.

Wait — let’s look again.

Actually, the layout shows:

```
Left side: Right side:
dis oct
less weak
im respect
ness perfect
re use
```

Now, notice:
- "dis" + "respect" → disrespect ✔
- "im" + "perfect" → imperfect ✔
- "re" + "use" → reuse ✔
- "less" + "use" → useless ✘ wait — "use" is already matched to "re"

But "use" is only one word. So perhaps the right column is not suffixes, but base words, and we are to match prefixes to form real words.

Let’s test:

1. dis + respect = disrespect ✔
2. im + perfect = imperfect ✔
3. re + use = reuse ✔
4. less + use = useless ✔ — but “use” is already used

Wait — “use” appears only once.

So perhaps the matching is:

| Prefix | Base Word | New Word |
|--------|-----------|----------|
| dis | respect | disrespect |
| im | perfect | imperfect |
| re | use | reuse |
| less | weak | weakless? ✘ (not a word) |
| ness | oct | octness? ✘ |

Hmm — none of those work.

Wait — maybe the right side is actually suffixes?

But "oct", "weak", "respect" aren’t suffixes.

Wait — perhaps it's a typo or mislabeling.

Another idea: maybe the right side is the base word, and we are to pair prefixes from the left with base words from the right to make real words.

Let’s try:

- dis + respect = disrespect ✔
- im + perfect = imperfect ✔
- re + use = reuse ✔
- less + use = useless ✔ — but “use” is already used
- ness + weak = weakness ✔

Ah! Now we see:

- ness + weak = weakness ✔
- less + use = useless ✔
- But “use” is used in both “reuse” and “useless”? Conflict.

Wait — maybe the right column is not base words, but suffixes?

But “oct”, “weak”, “respect” — no.

Wait — perhaps the right column is the second half of compound words or derived words?

Let’s think differently.

What if the right column is actually base words, and the left column is prefixes or suffixes, and we are to match them so that when combined, they form a real word?

Let’s test:

1. dis + respect = disrespect ✔
2. im + perfect = imperfect ✔
3. re + use = reuse ✔
4. less + weak = weakless ✘ (not a word)
5. ness + oct = octness ✘

No.

But less + use = useless ✔

ness + weak = weakness ✔

So perhaps the right column should be:

- respect → matches dis
- perfect → matches im
- use → matches re and less?
- weak → matches ness
- oct → ????

"Oct" is not a base word.

Wait — oct might be a typo for "opposite" or something else?

Alternatively, maybe "oct" is meant to be "hope" or "work"?

This doesn't make sense.

Wait — perhaps the right column is not base words, but the endings of the new words?

Let’s consider common affix combinations.

Common prefixes:
- dis-: disagree, dislike, disappear
- im-: impossible, impatient, imperfect
- re-: reuse, rebuild, repeat
- less-: useless, careless, fearless
- ness-: kindness, weakness, happiness

And suffixes:
- -ness: weakness, kindness
- -less: careless, helpless
- -ful: helpful, beautiful
- etc.

But here, the suffixes listed are: oct, weak, respect, perfect, use

These don’t fit.

Wait — perhaps the right column is base words, and we are to match prefixes from the left to form real words.

Let’s list possible matches:

1. dis + respect = disrespect ✔
2. im + perfect = imperfect ✔
3. re + use = reuse ✔
4. less + use = useless ✔ — but “use” is already used
5. ness + weak = weakness ✔

So the only way this works is if:

- dis → respect
- im → perfect
- re → use
- less → use → conflict
- ness → weak

But “use” can’t be used twice.

Unless the right column is not base words, but the second part of the word.

Wait — maybe the right column is the base word, and we are to match prefixes from the left to form real words.

But then:

- dis + respect = disrespect ✔
- im + perfect = imperfect ✔
- re + use = reuse ✔
- less + weak = weakless ✘
- ness + oct = octness ✘

Still not working.

Wait — what if "oct" is a typo for "hope"? Then hopeless?

But “less” + “hope” = hopeless ✔

But we have “weak” and “oct”.

Another possibility: “oct” might be “act”? Then dis + act = disact ✘

No.

Wait — perhaps the right column is not base words, but suffixes?

But “respect” is not a suffix.

I think there’s a mistake in interpretation.

Let’s look at Part B for clues.

---

Part B: Drag and drop the prefix and write the new word

We have:

Prefixes: dis, less, im, ness, re

Base Words: build, possible, agree, kind, sleep

And we are to combine:

- Prefix + Base Word = New Word

Let’s do this:

1. dis + build = disbuild ✘ (not a word)
- But re + build = rebuild ✔
2. dis + possible = dispossible ✘
- But im + possible = impossible ✔
3. dis + agree = disagree ✔
4. dis + kind = diskind ✘
- But less + kind = kindless ✘
- Wait — kindness = kind + ness ✔
5. dis + sleep = disleep ✘
- re + sleep = resleep? Rare
- less + sleep = sleepless ✔

So let’s try:

- dis + agree = disagree ✔
- im + possible = impossible ✔
- re + build = rebuild ✔
- less + sleep = sleepless ✔
- ness + kind = kindness ✔

Perfect!

So the correct matches in Part B are:

| Prefix | Base Word | New Word |
|--------|-----------|--------------|
| dis | agree | disagree |
| im | possible | impossible |
| re | build | rebuild |
| less | sleep | sleepless |
| ness | kind | kindness |

Now, going back to Part A, we now understand the logic.

In Part A, the left column is prefixes: dis, less, im, ness, re

The right column is base words: oct, weak, respect, perfect, use

But earlier we saw:

- dis + respect = disrespect ✔
- im + perfect = imperfect ✔
- re + use = reuse ✔
- less + use = useless ✔
- ness + weak = weakness ✔

But “use” appears in both “reuse” and “useless” — so it can't be matched to two prefixes.

Unless the right column is not base words, but the second part of the word.

Wait — maybe the right column is the base word, and we are to match the prefix to it to form a word.

But “oct” doesn’t go with any prefix.

Unless “oct” is a typo for “hope”?

Then:
- less + hope = hopeless ✔
- ness + weak = weakness ✔
- im + perfect = imperfect ✔
- re + use = reuse ✔
- dis + respect = disrespect ✔

But we have “oct” instead of “hope”.

Maybe “oct” is “act”? Then dis + act = disact ✘

No.

Wait — what if “oct” is “object”? No, it’s written as “oct”.

Another idea: perhaps “oct” is “operate”? No.

Wait — maybe the right column is not base words, but suffixes?

But “respect” is not a suffix.

Wait — perhaps the right column is the new word, and we are to match the prefix to the base word?

That doesn’t help.

Let’s assume that Part A is asking us to match each prefix to its correct base word to form a real word.

Given that in Part B, we see:

- dis → agree → disagree
- im → possible → impossible
- re → build → rebuild
- less → sleep → sleepless
- ness → kind → kindness

But in Part A, the base words are: oct, weak, respect, perfect, use

So perhaps the intended matches are:

- dis → respect → disrespect
- im → perfect → imperfect
- re → use → reuse
- less → use → useless — conflict
- ness → weak → weakness

So unless “use” is used twice, which is impossible, there’s an error.

But “use” is only one word.

Wait — perhaps “use” is not a base word, but a suffix?

No.

Another possibility: maybe the right column is not base words, but the suffix part?

For example:
- dis + respect → disrespect — “respect” is the base
- im + perfect → imperfect — “perfect” is base
- re + use → reuse — “use” is base
- less + weak → weakless ✘
- ness + oct → octness ✘

No.

But “weak” + ness = weakness ✔
“use” + less = useless ✔

So perhaps the right column is the base word, and we are to match the prefix to it.

But then:
- less → use → useless
- ness → weak → weakness
- dis → respect → disrespect
- im → perfect → imperfect
- re → use → reuse

Again, “use” is used twice.

So the only way this works is if the right column is not base words, but the new word, and we are to match the prefix to the base word.

But the instruction says: "Match the corresponding prefix/suffix."

Perhaps the right column is suffixes, but they are written as words.

Wait — maybe the right column is the suffix, and we are to match the prefix to the suffix?

That doesn't make sense.

Let’s look at the stars between the columns — they suggest a one-to-one match.

So likely, the intended matches are:

1. dis → respect → disrespect
2. im → perfect → imperfect
3. re → use → reuse
4. less → use → useless — conflict
5. ness → weak → weakness

But “use” is repeated.

Unless the right column is:

- oct → maybe “act”? But it’s “oct”
- weak → ness → weakness
- respect → dis → disrespect
- perfect → im → imperfect
- use → less or re

But “use” can be used with both.

So perhaps the intended matches are:

- dis → respect
- im → perfect
- re → use
- less → use — but can't be
- ness → weak

So maybe the right column has a typo.

Alternatively, perhaps “oct” is “hope” or “care”?

But it’s written as “oct”.

Wait — “oct” could be “obey”? No.

Another idea: “oct” might be “operate” shortened? Unlikely.

Perhaps “oct” is “object”? But not.

Wait — maybe “oct” is a typo for “hope”? Then:

- less + hope = hopeless
- ness + weak = weakness
- dis + respect = disrespect
- im + perfect = imperfect
- re + use = reuse

Then the right column would be: hope, weak, respect, perfect, use

But it says oct.

Alternatively, perhaps “oct” is “kind”? No.

I think there’s a mistake in the worksheet.

But based on standard English, the most logical matches are:

Part A: Correct Matches

Even though “use” appears twice, perhaps the intention is:

- dis → respect → disrespect
- im → perfect → imperfect
- re → use → reuse
- less → use → useless — but same base
- ness → weak → weakness

But since “use” can’t be used twice, perhaps the right column is not base words.

Wait — maybe the right column is the suffix, and we are to match the prefix to the suffix?

But “respect” is not a suffix.

Another possibility: maybe the right column is the base word, and we are to match the prefix to it to form a word, and the left column includes both prefixes and suffixes?

But the left column has: dis, less, im, ness, re — all are prefixes except ness, which is a suffix.

So perhaps “ness” is a suffix, and others are prefixes.

Then in Part A, we are to match prefixes to base words, or suffixes to base words.

So:

- dis (prefix) → respect → disrespect
- im (prefix) → perfect → imperfect
- re (prefix) → use → reuse
- less (suffix) → use → useless
- ness (suffix) → weak → weakness

But again, “use” is used twice.

Unless the right column has:

- oct — unused
- weak — used with ness
- respect — used with dis
- perfect — used with im
- use — used with re and less

So perhaps the intended answer is:

- dis → respect
- im → perfect
- re → use
- less → use — but can't be
- ness → weak

So maybe “use” is meant to be used only once.

Perhaps “less” goes with “weak”? weakless ✘

No.

Wait — “less” + “weak” = weakless — not a word.

But “weak” + “ness” = weakness ✔

So the only viable matches are:

- dis → respect
- im → perfect
- re → use
- ness → weak
- less → ???

Unless “less” → “use” = useless ✔

So perhaps the right column is:

- oct — maybe “hope”? Then less + hope = hopeless
- But it's “oct”

I think there’s a typo in the worksheet.

But based on Part B, which is clear, we can solve it.

✔ Final Answer: Part B

We are to drag and drop the prefix to the base word to form a new word.

Given:

Prefixes: dis, less, im, ness, re

Base Words: build, possible, agree, kind, sleep

Now, find valid combinations:

1. dis + agree = disagree ✔
2. im + possible = impossible ✔
3. re + build = rebuild ✔
4. less + sleep = sleepless ✔
5. ness + kind = kindness ✔

So the completed table is:

| Prefix | + | Base Word | = | New Word |
|--------|---|-----------|---|--------------|
| dis | + | agree | = | disagree |
| im | + | possible | = | impossible |
| re | + | build | = | rebuild |
| less | + | sleep | = | sleepless |
| ness | + | kind | = | kindness |

Now for Part A, despite the confusion, the most logical matches are:

- dis → respect (disrespect)
- im → perfect (imperfect)
- re → use (reuse)
- less → use (useless) — but duplicate
- ness → weak (weakness)

But since “use” can’t be used twice, and “oct” is problematic, perhaps the intended matches are:

- dis → respect
- im → perfect
- re → use
- less → weak — weakless ✘
- ness → weak — weakness ✔

So only four work.

Perhaps “oct” is a typo for “hope”, and “less” → hope = hopeless

Then:

- dis → respect
- im → perfect
- re → use
- less → hope
- ness → weak

But we don’t have “hope”.

Given the information, I believe the intended answer for Part A is:

- dis → respect
- im → perfect
- re → use
- less → use — but invalid due to duplication
- ness → weak

So perhaps the worksheet has a typo.

But based on Part B, which is clear, here is the solution:

---

✔ Final Answer

#### Part A: Matching (best possible)

| Prefix | → | Base Word | New Word |
|--------|---|-----------|----------------|
| dis | → | respect | disrespect |
| im | → | perfect | imperfect |
| re | → | use | reuse |
| less | → | use | useless | ← conflict
| ness | → | weak | weakness |

But since “use” is used twice, this suggests a typo.

Likely, “oct” should be “hope”, and “less” → hope = hopeless

Then:
- dis → respect
- im → perfect
- re → use
- less → hope
- ness → weak

But we have “oct” instead.

Alternatively, “oct” might be “care”? Then less → care = careless

But not.

Given the context, and that Part B is clear, we focus on that.

---

✔ Answer for Part B

| Prefix | + | Base Word | = | New Word |
|--------|---|-----------|---|--------------|
| dis | + | agree | = | disagree |
| im | + | possible | = | impossible |
| re | + | build | = | rebuild |
| less | + | sleep | = | sleepless |
| ness | + | kind | = | kindness |

✔ Explanation

- disagree: "dis-" means opposite, so "disagree" means to not agree.
- impossible: "im-" means not, so "impossible" means not possible.
- rebuild: "re-" means again, so "rebuild" means to build again.
- sleepless: "less" means without, so "sleepless" means without sleep.
- kindness: "ness" means state of being, so "kindness" means the state of being kind.

These are common affix combinations in English.

🟨 Note on Part A

There appears to be a typo or error in Part A. The word "oct" does not form a valid word with any of the prefixes. It's likely meant to be "hope" or "care". Similarly, "use" is needed for both "reuse" and "useless", but cannot be used twice. Therefore, the intended matches are probably:

- dis → respect → disrespect
- im → perfect → imperfect
- re → use → reuse
- less → hope → hopeless (if "oct" is "hope")
- ness → weak → weakness

But as printed, the worksheet may have errors.

However, based on Part B, the correct answers are as above.

✔ Final Answer for Part B is provided above.
