Conjunctions Worksheets | Correlative Conjunctions Fill-In Worksheet - Free Printable

Let’s go through each sentence one by one. We’re choosing between either/or or neither/nor, depending on what makes sense in the sentence.

Remember:
- Use either...or when you’re talking about two choices, and at least one is true or possible.
- Use neither...nor when both options are NOT true or NOT happening.

1. We ________ are going to the park _______ are going home.

This sounds like we’re saying: “We are not going to the park, and we are also not going home.” So it’s negative for both → use neither / nor.

→ *We neither are going to the park nor are going home.*

Wait — that doesn’t sound quite right grammatically. Let’s fix the word order.

Actually, with “neither/nor”, we usually say:
*We are neither going to the park nor going home.*
But the blanks are placed as:
“We ________ are going to the park _______ are going home.”

So maybe it’s meant to be:
*We are neither going to the park nor going home.* → but the structure given has “are” after the first blank.

Hmm… perhaps the intended answer is still neither / nor, even if the phrasing is a bit awkward.

Alternatively, maybe it’s trying to say:
“We either are going to the park or are going home.” → meaning we’ll do one of those two things.

That actually makes more sense! Because “we are going to do one thing or the other”.

So let’s try either / or:

→ *We either are going to the park or are going home.*

Yes — that works. It means we will do one of these two things.

✔ Final choice for #1: either / or

2. ________ James _________ expressed their thoughts.

This seems incomplete. Who else? Maybe it’s supposed to be “James and someone else”? But as written, it says “James ___ expressed their thoughts” — which implies maybe James didn’t express them, and someone else didn’t either?

Wait — look again: “________ James _________ expressed their thoughts.”

It might mean: “Neither James nor [someone] expressed their thoughts.” But there’s no second person named.

Perhaps it’s a typo, and it should be “James and Sharon” or something? But based on what’s here...

Another possibility: Maybe it’s “Either James or [someone] expressed...” — but again, no second subject.

Wait — looking back at the worksheet, question 3 mentions “the cousins” and “Sharon”, so maybe this one is missing a name? But we have to work with what’s given.

Actually, re-reading: “________ James _________ expressed their thoughts.”

If we put Neither / nor, it would be:
*Neither James nor [implied someone] expressed their thoughts.* — but that’s incomplete.

If we put Either / or, it would be:
*Either James or [someone] expressed their thoughts.* — again, incomplete.

But notice: the verb is “expressed” (past tense), and “their thoughts” — plural possessive. That suggests more than one person.

Maybe it’s supposed to be: “Neither James nor his friend expressed their thoughts.” But since it’s not written, perhaps the worksheet expects us to assume the structure.

Looking at common usage, this kind of sentence often uses neither/nor when negating two subjects.

But without a second subject, it’s tricky.

Wait — perhaps it’s a mistake, and it should be “James and Sharon” like in #3? Or maybe it’s “James or Mary”?

Since we can’t change the sentence, let’s think logically.

The most natural fit is Neither / nor, assuming an implied second person. For example:
*Neither James nor anyone else expressed their thoughts.*

But strictly speaking, the sentence as written is incomplete. However, in many worksheets, they expect you to fill in the conjunctions even if the sentence is slightly off.

Alternatively, maybe it’s “Either James or he expressed...” — no, that doesn’t make sense.

Let me check online or recall standard examples.

Actually, I remember a similar example: “Neither John nor Jane came.” So if this were “Neither James nor Sarah expressed...”, it would work.

Given that, and since the worksheet gives only two options per question, and this is likely testing recognition of correlative pairs, I think the intended answer is Neither / nor, implying a second unstated subject.

But wait — let’s look at question 3: it has “the cousins” and “Sharon”, so probably question 2 is missing a name. Perhaps it’s a typo, and it should be “James and Lisa” or something.

To move forward, I’ll assume it’s meant to be a negative statement about two people, so neither / nor.

✔ Final choice for #2: Neither / nor

*(Note: In real life, this sentence needs a second subject, but for worksheet purposes, we’ll go with this.)*

3. ________ the cousins _______ Sharon told the truth.

This is clearer. Two groups: “the cousins” and “Sharon”. The verb is “told the truth” — past tense.

If we say “Either the cousins or Sharon told the truth,” that means one of them did.

If we say “Neither the cousins nor Sharon told the truth,” that means none of them did.

Which one fits? The sentence doesn’t give context, so we need to see which conjunction pair makes grammatical sense.

Both could work, but typically in such exercises, they want you to choose based on logic or common usage.

Actually, looking at the pattern, all questions give the same two options: (either/or), (neither/nor). So we must pick one.

In English, when we say “X or Y did something”, it’s affirmative; “neither X nor Y did” is negative.

Here, since there’s no negation word like “not”, it’s more likely to be either / or.

For example: “Either the cousins or Sharon told the truth.” — meaning one of them is truthful.

Whereas “Neither the cousins nor Sharon told the truth” would require a negative context, which isn’t present.

So I think either / or is better here.

✔ Final choice for #3: Either / or

---

4. At night ________ the cats _______ the dogs wake us up.

Again, two subjects: cats and dogs.

If we say “Either the cats or the dogs wake us up,” that means sometimes one, sometimes the other.

If we say “Neither the cats nor the dogs wake us up,” that means they don’t wake us up at all.

The phrase “At night” suggests it happens regularly, so probably they DO wake us up — so either / or makes sense.

Also, “wake” is present tense, indicating habitual action.

So: “At night, either the cats or the dogs wake us up.” — perfect.

✔ Final choice for #4: Either / or

---

5. John will ________ start today _______ start tomorrow.

Two options: start today or start tomorrow.

This is clearly a choice between two possibilities.

So: “John will either start today or start tomorrow.”

That’s straightforward.

✔ Final choice for #5: either / or

---

Now, let’s summarize:

1. either / or
2. neither / nor *(with note that sentence may be incomplete)*
3. either / or
4. either / or
5. either / or

But wait — for #2, let’s double-check.

Original: “________ James _________ expressed their thoughts.”

If we use Neither / nor, it becomes: “Neither James nor [someone] expressed their thoughts.” — but who is “nor” referring to? It’s missing.

If we use Either / or, it becomes: “Either James or [someone] expressed their thoughts.” — again, missing someone.

However, in some contexts, “their” might refer to James alone (though traditionally “his”), but modern usage accepts “their” for singular.

But still, the structure requires two subjects for correlative conjunctions.

Perhaps it’s a trick, and it’s supposed to be “James himself” or something.

Another idea: maybe it’s “Neither James nor he expressed...” — no.

I recall that sometimes in informal speech, people say “Neither James expressed...” but that’s incorrect grammar.

Upon second thought, looking at the example in the worksheet: “She either wants to play or not.” — which is a bit odd too, but acceptable.

For #2, perhaps the intended answer is Neither / nor, and the second subject is implied from context.

Maybe it’s “James and his brother” but not written.

To stay consistent with typical worksheet answers, and since “neither/nor” is used for negatives, and “expressed their thoughts” might imply they didn’t, I’ll stick with neither / nor.

Final decision:

1. either / or
2. neither / nor
3. either / or
4. either / or
5. either / or

Now, writing the filled sentences:

1. We either are going to the park or are going home.
2. Neither James nor expressed their thoughts. ← still awkward, but we'll go with it.
Actually, upon reflection, this might be a error in the worksheet. Perhaps it should be "James and Lisa" or similar. But since we must answer, I'll leave it.

Wait — let's read it again: "________ James _________ expressed their thoughts."

What if it's "Either James or he expressed..." — no.

Another possibility: maybe it's "Neither James nor anyone expressed..." but not written.

I think for accuracy, in standard English, this sentence is flawed, but for the purpose of this exercise, the expected answer is likely neither / nor.

Perhaps the second blank is for the second subject, but it's not provided. Looking at the spacing, it's "________ James _________ expressed", so the first blank is before James, second after James.

So: [conjunction] James [conjunction] expressed...

That would be like: "Neither James nor expressed" — which is wrong because "nor" should be followed by a noun/pronoun.

Unless it's "Neither James nor did he express" — but that's not the structure.

I think there might be a typo in the worksheet. Perhaps it's supposed to be "James and Sharon" like in #3.

To resolve this, let's assume that for #2, it's meant to be a negative statement, so neither / nor, and the second subject is omitted by mistake.

So I'll proceed.

Final Answers:

1. either, or
2. Neither, nor
3. Either, or
4. either, or
5. either, or

Now, for the final answer section, I'll list them as requested.

Final Answer:
1. either, or
2. Neither, nor
3. Either, or
4. either, or
5. either, or
