Correlative conjunctions: rules and examples
What are correlative conjunctions and how do they work?
Correlative conjunctions are paired words such as 'both...and', 'either...or', 'neither...nor' and 'whether...or'. They connect balanced grammatical structures to add, offer alternatives, exclude possibilities or explore uncertainty. For example, 'The service is both efficient and reliable.' Keep both sides parallel, and match the verb to the nearer subject when necessary.
Key points
- 'Both...and' adds two people, things or qualities.
- 'Either...or' presents two possible alternatives.
- 'Neither...nor' excludes both alternatives without a negative verb.
- 'Whether...or' explores possibilities or uncertain conditions.

| Form | Use it for | Example |
|---|---|---|
| both...and | Adds two elements together | The service is both efficient and reliable. |
| either...or | Offers two alternatives | You can either stay here or join us later. |
| neither...nor | Excludes two alternatives | Neither plan nor proposal seems practical. |
| whether...or | Explores two possibilities | Check whether the parcel arrived or was delayed. |
The full explanation
A correlative conjunction consists of two linked words that show how two thoughts connect. Both...and combines two things together. Either...or offers a choice between two options. Neither...nor rejects two alternatives at once. Whether...or investigates two possible conditions or outcomes.
Both the project supervisor and the field technicians approved the updated safety guidelines.
Why it works: Both...and links two subjects together, requiring the plural verb approved.

Spotting paired words in a sentence
Correlative conjunctions always operate in two parts that link balanced elements across a sentence. Instead of relying on a single linking word such as and or but, these expressions surround the two items being compared. When you spot the first word of the pair, your ear expects the second word to appear shortly afterward. Recognizing the complete pair helps you follow complex workplace instructions and spoken announcements without losing track of the main idea.
-
Both the design team and the marketing group approved the new schedule.
Why it works: Both and and work together to frame two equal teams who share the action.
-
You can either leave your luggage at reception or carry it to the meeting room.
Why it works: Either signals the first action, and or introduces the second action.
Your turn
Which pair of words functions as a correlative conjunction in standard English?
Answer: neither...nor
Show the answer
Answer: neither...nor
In standard English, neither pairs strictly with nor to exclude two alternatives, whereas both pairs with and and either pairs with or.
Adding two elements with both and and
The pair both...and emphasizes that two distinct people, objects, or conditions are included simultaneously. Unlike a solitary and, using both right before the first element creates equal emphasis and prepares the listener for two items. Because two subjects joined by both...and combine their numbers, the verb that follows them is almost always plural in everyday English sentences. Place both directly before the first linked item so the balance remains obvious to your reader.
-
Both Marcus and Elena work in the regional logistics office.
Why it works: Because two people are joined by both...and, the verb work takes a plural form.
-
The apartment is both spacious and affordable for new residents.
Why it works: Both links two single adjectives that describe the condition of the apartment.

Your turn
Which sentence uses both...and with the correct plural verb form?
Answer: Both the manager and the supervisor work late on Thursdays.
Show the answer
Answer: Both the manager and the supervisor work late on Thursdays.
When both...and links two singular subjects, the resulting compound subject is plural and requires the base plural verb work.
Presenting choices with either and or
When you want to present two distinct alternatives where only one will happen or apply, use the pair either...or. Placing either before the first alternative clarifies that a choice exists before the listener hears the rest of the clause. This structure prevents misunderstandings in scheduling, travel arrangements, and project plans. Ensure that you do not substitute nor or and when framing an open choice between two mutually exclusive actions.
-
We can either reschedule the interview or conduct it online.
Why it works: Either...or links two base verb phrases, giving the candidate one choice between two options.
-
You may choose either the morning session or the afternoon workshop.
Why it works: The pair connects two noun phrases representing alternative time slots.
Your turn
Which sentence correctly presents two alternatives for submitting a form?
Answer: You can either mail the form or bring it in person.
Show the answer
Answer: You can either mail the form or bring it in person.
Either must pair with or when offering two possible choices, making either mail... or bring the correct structure.
Excluding two choices with neither and nor
The pair neither...nor denies or excludes two possibilities at the same time, stating that the first condition is not true and the second condition is also not true. Because neither and nor already carry negative meaning, the accompanying verb must remain affirmative to avoid creating an unintended double negative. Using neither with or is a frequent error among learners; remember that the negative partner for neither is always nor in formal and standard English.
-
Neither Clara nor David answered the emergency phone call.
Why it works: The negative meaning is expressed by neither...nor, so the verb answered remains affirmative.
-
The hotel room was neither clean nor quiet during our stay.
Why it works: Two descriptive adjectives are joined by neither...nor to show both qualities were absent.
Your turn
Which sentence expresses negative exclusion without creating a double negative?
Answer: Neither the monitor nor the keyboard was working properly.
Show the answer
Answer: Neither the monitor nor the keyboard was working properly.
Neither pairs strictly with nor, and the verb was working must be affirmative because the conjunctions already establish the negative meaning.
Weighing possibilities with whether and or
Use whether...or when you need to introduce two alternative conditions or possibilities, especially after verbs of inquiry such as ask, decide, know, or check. Unlike either...or, which often commands an action or specifies one outcome, whether...or frequently explores uncertainty or indicates that an outcome remains identical regardless of which condition occurs. Make sure you place whether before the first condition and or immediately before the alternative condition.
-
We need to verify whether the client approved the contract or requested changes.
Why it works: Whether...or explores two possible states of the contract after the verb verify.
-
Whether we take the express train or travel by bus, the arrival time is identical.
Why it works: The pair introduces two possible travel modes that lead to the same final result.
Your turn
Complete the sentence to explore two possibilities: 'Our director asked ___ the report was finished ___ still in review.'
Answer: whether / or
Show the answer
Answer: whether / or
Whether...or correctly introduces two uncertain conditions after an inquiry verb like asked.
Matching grammatical forms on both sides
Parallel structure requires that the grammatical unit following the first conjunction matches the grammatical unit following the second conjunction. If you place a prepositional phrase after either, you must place another prepositional phrase after or. Mixing different parts of speech, such as putting an infinitive verb after the first word and a simple noun after the second word, creates awkward rhythm and slows down comprehension. Matching forms keeps your speech clear and your writing professional.
-
She wants either to study accounting or to master computer programming.
Why it works: Both sides use full infinitive verbs (to study and to master), creating a parallel structure.
-
The technician checked both under the desk and behind the server rack.
Why it works: Two prepositional phrases (under the desk and behind the server rack) match identically.
Your turn
Which sentence maintains parallel grammatical structure after both conjunctions?
Answer: He decided either to rent a small van or to buy a used trailer.
Show the answer
Answer: He decided either to rent a small van or to buy a used trailer.
Both parts after the conjunctions use an infinitive phrase (to rent and to buy), which maintains parallel structure.
Choosing the correct verb for split subjects
When either...or or neither...nor connects two subjects with different numbers, such as one singular noun and one plural noun, subject-verb agreement follows the proximity rule. In standard edited English, the verb agrees with whichever subject noun stands closest to it in the sentence. If the nearer subject is plural, select a plural verb; if the nearer subject is singular, select a singular verb. Placing the plural noun second often sounds smoother to native listeners.
-
Neither the head chef nor the kitchen assistants are ready to begin service.
Why it works: The subject assistants is plural and stands closest to the verb, so the plural verb are is required.
-
Either the senior partners or the lead architect is presenting the design today.
Why it works: The subject architect is singular and stands nearest to the verb, so the singular verb is fits.
Your turn
Which verb correctly completes the sentence: 'Neither the lead singer nor the musicians ___ satisfied with the sound rehearsal'?
Answer: are
Show the answer
Answer: are
Under the proximity rule, the plural subject musicians is closest to the verb, requiring the plural form are.
Listening for stress and sentence pauses
In natural spoken English, correlative conjunctions follow distinct rhythm patterns that help you anticipate information before the speaker finishes. The first word of the pair receives moderate stress and a slightly rising pitch, signaling that a linked item will follow soon. The second word usually has lighter stress and is followed immediately by the second item. Notice how speakers rarely place pauses between the conjunction and the linked noun, maintaining steady flow within each parallel half.
-
We can meet either at noon or after three o'clock.
Why it works: Either carries upward intonation, while or connects smoothly to the following time phrase.
-
Both the pilot and the copilot confirmed the flight path.
Why it works: Slight stress on Both warns the listener that two people will share the statement.
Your turn
What intonation pattern typically signals the first half of a correlative pair in speech?
Answer: A slightly rising pitch that indicates another connected item is coming.
Show the answer
Answer: A slightly rising pitch that indicates another connected item is coming.
Speakers often use a slightly rising pitch on the first conjunction to signal that a second related item will complete the idea.
Common mistakes
What learners often say, what to say instead, and why.
-
Not this:
The proposal is both realistic or affordable.Say: The proposal is both realistic and affordable.
'Both' pairs with 'and', not 'or', when adding two qualities.
-
Not this:
Neither the assistant nor the managers isn't available.Say: Neither the assistant nor the managers are available.
'Neither...nor' takes an affirmative verb, and 'are' agrees with the nearer plural subject, 'managers'.
-
Not this:
She chose either to work remotely or attending the conference.Say: She chose either to work remotely or to attend the conference.
Both alternatives need matching infinitive structures.
-
Not this:
We do not know whether the parcel arrived nor was delayed.Say: We do not know whether the parcel arrived or was delayed.
'Whether' pairs with 'or' when introducing two possible conditions.
Before you go
Remember this
Select the pair that matches your intended communicative purpose, balance the grammatical structure on both sides, and verify subject-verb agreement using the proximity rule when choices differ in number.

Questions about "Correlative conjunctions: rules and examples"
How do I choose the correct verb when either...or connects a singular and a plural noun?
In standard written English, use the proximity rule. This means the verb matches the noun that is physically closest to it in the sentence. If the noun nearest to the verb is singular, use a singular verb. If the nearest noun is plural, use a plural verb.

Either the students or the teacher is preparing the classroom.
What is the difference between either...or and whether...or?
Use either...or when you present a choice between two actions or items where one will happen. Use whether...or when you investigate two possibilities, express doubt, or describe a situation where the outcome remains unchanged under both conditions.
You can either take the bus or walk to the clinic.
I do not know whether the bus or the subway is faster today.
Can I use a negative verb like 'do not' or 'is not' with neither...nor?
No, do not use a negative verb with neither...nor. Because neither and nor already carry negative meaning, adding another negative word produces a double negative in standard English. Always pair neither...nor with an affirmative verb form.
Neither the printer nor the scanner works today.
Neither Arthur nor Lisa was available for the call.
What does parallel structure mean with correlative conjunctions?
Parallel structure means placing identical grammatical forms directly after each half of the pair. If an infinitive verb follows the first conjunction, an infinitive verb should follow the second. This symmetry makes sentences easier to read and understand.
