Either vs neither can be confusing because both words are used when talking about two people, things, or choices. However, they have opposite meanings. Either generally refers to one of two choices or allows a choice between two possibilities, while neither means not one and not the other.
Understanding the difference between either and neither can help you write clearer sentences and avoid common grammar mistakes.
The simplest rule is:
- Either = one of two, or one choice from two possibilities
- Neither = not one and not the other
For example:
- Either answer is acceptable.
- Neither answer is correct.
In the first sentence, one of the two answers can be acceptable. In the second, both answers are incorrect.
What Does Either Mean?
Either is commonly used when referring to two people, things, choices, or possibilities. It can mean one or the other of two.
For example:
You can choose either option.
This means you can choose option A or option B.
Another example is:
Either dress would look good for the event.
This means the speaker considers both dresses suitable, and the person can choose one of them.
Examples of Either
- You can sit on either side of the table.
- Either answer could be correct.
- We can meet on either Monday or Tuesday.
- You can take either road to the city.
- Either candidate can complete the task.
- I don’t like either of these options.
- She hasn’t visited either restaurant.
The exact meaning of either depends on how it is used in a sentence.
What Does Neither Mean?
Neither means not one and not the other of two people or things.
For example:
Neither answer is correct.
This means answer A is not correct, and answer B is not correct.
Another example is:
Neither John nor Mark attended the meeting.
This means John did not attend, and Mark did not attend.
Examples of Neither
- Neither option is suitable.
- Neither answer is correct.
- Neither student finished the assignment.
- Neither restaurant is open.
- Neither candidate agreed with the proposal.
- Neither book belongs to me.
- Neither explanation makes sense.
Because neither already has a negative meaning, it generally does not need another negative word.
Either vs Neither: The Main Difference
The most important difference between either and neither is their meaning.
| Word | Basic Meaning | Example |
|---|---|---|
| Either | One or the other of two | You can choose either option. |
| Neither | Not one and not the other | Neither option is available. |
Think of the two words this way:
Either = A or B
Neither = Not A and not B
For example:
You can choose either coffee or tea.
This means coffee is available, tea is available, and you may choose one.
Compare that with:
You can choose neither coffee nor tea.
This means you cannot choose coffee or tea.
Either and Neither With “Or” and “Nor”
One of the most common grammatical patterns is:
either + A + or + B
and
neither + A + nor + B
These structures are called correlative conjunctions because the two words work together.
Either…or
Use either…or when presenting two alternatives.
Examples:
- You can either call me or send me an email.
- We can either leave now or wait until tomorrow.
- Either Sarah or Emily will lead the meeting.
- He will either study at home or go to the library.
- You can either take the bus or walk.
The basic pattern is:
Either + choice A + or + choice B
Neither…nor
Use neither…nor when saying that both alternatives are excluded.
Examples:
- Neither Sarah nor Emily attended the meeting.
- I want neither coffee nor tea.
- Neither answer nor explanation was convincing.
- He speaks neither French nor German.
- Neither restaurant nor café is open.
The basic pattern is:
Neither + choice A + nor + choice B
Either vs Neither in Positive Sentences
Either is frequently used in positive statements involving two choices.
For example:
Either option will work.
This means option A will work, and option B will also work. The speaker is saying that either one can be selected.
Other examples include:
- Either route will take you downtown.
- Either answer could be accepted.
- Either shirt looks good on you.
- Either method can solve the problem.
Here, either does not necessarily mean that only one option is good. It can mean that one of the two choices is acceptable.
Either in Negative Sentences
Either can also appear in negative sentences, especially at the end of a sentence.
For example:
I don’t like either option.
This means the speaker does not like option A or option B.
Another example:
She doesn’t want either dress.
This means she does not want dress A or dress B.
This use of either can be confusing because either itself is not necessarily negative. The negative meaning comes from the word not.
Compare:
I like either option.
This suggests either option is acceptable.
I don’t like either option.
This means neither option is liked.
In many cases, the second sentence can be rewritten with neither:
I don’t like either option.
=
I like neither option.
Both communicate essentially the same idea.
Neither Is Already Negative
A common mistake is using neither with another negative word.
For example, this sentence is generally considered incorrect in standard English:
I don’t like neither option.
The problem is that don’t and neither both create a negative construction.
A clearer standard-English version is:
I like neither option.
Or:
I don’t like either option.
The same principle applies to other sentences.
Incorrect in standard English:
She didn’t invite neither John nor Mary.
Better:
She invited neither John nor Mary.
Or:
She didn’t invite either John or Mary.
For formal and standard US English, avoid unnecessary double negatives when using neither.
Either vs Neither as Determiners
Both either and neither can be used before singular countable nouns when referring to two things.
Examples with either:
- Either answer is acceptable.
- Either student can help.
- Either option will work.
- Either road leads to the town.
Examples with neither:
- Neither answer is correct.
- Neither student finished the assignment.
- Neither option is available.
- Neither road is safe.
Notice that the noun after either or neither is normally singular when these words refer directly to two individual choices.
Therefore, standard English uses:
Either option is acceptable.
and:
Neither option is acceptable.
Not:
Either options are acceptable.
or:
Neither options are acceptable.
Either and Neither With Singular Verbs
When either or neither is used as a determiner before a singular noun, the verb is generally singular.
Examples:
- Either choice is acceptable.
- Neither answer is correct.
- Either student has permission.
- Neither car is available.
- Either route works for us.
- Neither option seems practical.
This is an important rule to remember.
Correct:
Neither answer is correct.
Incorrect:
Neither answer are correct.
Because answer is singular, the verb should be is.
Either of vs Neither of
Another common structure is:
either of + plural noun/pronoun
and
neither of + plural noun/pronoun
Examples:
- Either of the answers is acceptable.
- Either of the students can help.
- Either of these restaurants is fine.
- Neither of the answers is correct.
- Neither of the students was available.
- Neither of these options works for me.
After either of or neither of, the noun or pronoun is usually plural.
For example:
Either of the two books is useful.
Neither of the two books is useful.
The verb generally remains singular in formal standard English when either or neither is the subject.
Either of vs Neither of With Pronouns
When using pronouns after either of or neither of, object pronouns are standard.
Examples:
- Either of them can help.
- Neither of them knows the answer.
- Either of us can drive.
- Neither of us wants to leave.
- Either of you can choose.
- Neither of you has answered the question.
These constructions are very common in everyday American English.
Either vs Neither When Talking About People
Both words can refer to people.
For example:
Either student can present the project.
This means student A or student B can present it.
Compare:
Neither student can present the project.
This means student A cannot present it, and student B cannot present it.
With names:
Either John or David will call you.
This means one of the two will call.
Neither John nor David will call you.
This means John will not call, and David will not call.
Either vs Neither in Questions
Either is often used when asking someone to choose between two alternatives.
For example:
Would you like either coffee or tea?
However, in natural conversation, speakers often say:
Would you like coffee or tea?
Another example:
Can either of you help me?
This asks whether at least one of two people can help.
Neither can also appear in questions, although it often creates a question about two negative possibilities.
For example:
Does neither option work for you?
This asks whether both options fail to work.
Either as an Adverb
Either has another important use. It can mean also in a negative sentence.
For example:
I don’t like the movie either.
This means another person has said they don’t like the movie, and the speaker agrees.
Compare:
I like the movie too.
with:
I don’t like the movie either.
In negative sentences, either can correspond to too or also in positive sentences.
More examples:
- I don’t understand it either.
- She doesn’t want to go either.
- We haven’t finished either.
- He can’t swim either.
- They don’t know the answer either.
This use of either is extremely common in everyday American English.
Neither as an Adverb
Neither can also be used to agree with a negative statement.
For example:
I don’t like coffee.
A response can be:
Neither do I.
This means:
I don’t like coffee either.
The structure neither + auxiliary verb + subject is commonly used to agree with a negative statement.
Examples:
I don’t like spicy food.
Neither do I.
Or:
She hasn’t finished the project.
Neither have I.
Or:
He can’t drive.
Neither can she.
This construction is more formal or structured than simply saying:
I don’t either.
Both forms are possible depending on the context.
Either vs Neither in Everyday Conversation
In everyday American English, either and neither appear frequently in conversations.
For example:
Person A: I don’t want pizza.
Person B: I don’t want it either.
Or:
Person A: I don’t want pizza.
Person B: Neither do I.
Both responses communicate agreement with the negative statement.
Similarly:
Person A: Which restaurant should we choose?
Person B: Either one is fine.
This means the speaker has no preference between the two restaurants.
If the speaker dislikes both options, they might say:
Neither one sounds good.
Common Mistakes With Either and Neither
Understanding common mistakes can make your writing more accurate.
Mistake 1: Using Neither With “or”
A common error is:
Neither John or Sarah came.
The standard construction is:
Neither John nor Sarah came.
Remember:
Either…or
Neither…nor
Mistake 2: Using Either With “nor”
Incorrect:
Either John nor Sarah will attend.
Correct:
Either John or Sarah will attend.
Mistake 3: Double Negatives With Neither
Incorrect in standard English:
I don’t want neither option.
Better:
I want neither option.
Or:
I don’t want either option.
Mistake 4: Using a Plural Noun Directly After Either
Incorrect:
Either options are good.
Correct:
Either option is good.
If you use either of, a plural noun can follow:
Either of the options is good.
Mistake 5: Using a Plural Verb With Neither
Incorrect:
Neither answer are correct.
Correct:
Neither answer is correct.
Mistake 6: Confusing Either With Both
Either generally focuses on one choice from two, while both refers to the two together.
Compare:
Either answer is acceptable.
This means you can choose one of the two answers.
Both answers are acceptable.
This means the two answers are acceptable.
The distinction is important because either and both do not communicate exactly the same idea.
Either vs Both
Consider these examples:
Either road will take you to the airport.
This means road A can take you there, and road B can also take you there. You need only one route.
Both roads lead to the airport.
This means the two roads lead there.
The focus is different:
- Either = one of two
- Both = the two together
Neither vs None
Neither is generally used when talking about two people or things.
None can be used for more than two.
For example:
Neither of the two answers is correct.
If there are five answers:
None of the five answers is correct.
This gives you a useful rule:
- Neither → two
- None → two or more, especially more than two
For example:
Neither candidate was available.
There are two candidates.
But:
None of the candidates was available.
There are three or more candidates.
Either vs Any
Either generally refers to two choices, while any is commonly used when there are three or more possibilities.
For example:
You can choose either of these two options.
But:
You can choose any of these five options.
This distinction is especially useful in formal writing.
Quick Comparison Examples
Here are several examples that make the difference clear:
Example 1
You can choose either book.
Meaning: You can choose one of the two books.
You can choose neither book.
Meaning: You cannot choose either book.
Example 2
Either restaurant is acceptable.
Meaning: One or the other restaurant is acceptable.
Neither restaurant is acceptable.
Meaning: Both restaurants are unacceptable.
Example 3
Either Sarah or Emma will attend.
Meaning: One of them will attend.
Neither Sarah nor Emma will attend.
Meaning: Both will not attend.
Example 4
I don’t like either movie.
Meaning: I don’t like movie A or movie B.
I like neither movie.
Meaning: I don’t like movie A or movie B.
A Simple Trick to Remember Either and Neither
If you regularly confuse these words, remember this:
EITHER = one of two
NEITHER = zero of two
You can also think of them mathematically:
Either = 1 out of 2
Neither = 0 out of 2
For example:
If you have two shirts and say:
Either shirt will work.
At least one choice can be selected.
If you say:
Neither shirt will work.
Both shirts are ruled out.
This simple distinction can help you choose the correct word quickly.
Either vs Neither: Final Rule
Use either when you are talking about one choice from two possibilities or when both possibilities are acceptable individually.
Use neither when you mean that not one and not the other is true, available, suitable, or acceptable.
Remember these two common patterns:
Either…or
Neither…nor
And remember the difference between these examples:
Either answer is correct.
One of the two answers can be selected.
Neither answer is correct.
Both answers are incorrect.
For negative sentences, you can often choose between:
I don’t like either option.
and:
I like neither option.
Both express the idea that neither option is liked.
FAQs
What is the difference between either and neither?
Either means one of two choices or possibilities, while neither means not one and not the other. For example, “Either answer is correct” means one of the two answers can be chosen, while “Neither answer is correct” means both answers are incorrect.
Is either positive or negative?
Either is generally neutral or positive when it means one of two choices. However, it can also be used in negative sentences, such as “I don’t like either option,” meaning that neither option is liked.
Is neither always negative?
Yes, neither has a negative meaning because it means “not one and not the other.” For example, “Neither student passed” means both students failed to pass.
What is the correct pair: either or or neither nor?
The standard pairs are either…or and neither…nor. For example, “You can either stay or leave” and “Neither John nor Sarah attended.”
Can I use neither with “or”?
In standard English, use neither…nor, not neither…or. The correct sentence is “Neither the blue shirt nor the black shirt fits me.”
Can either and neither be used with “of”?
Yes. Use either of or neither of when referring to two people or things. For example, “Either of these options is suitable” and “Neither of these options is suitable.”
What is the difference between either and both?
Either refers to one of two choices, while both refers to the two choices together. “Either answer is acceptable” means one answer can be chosen, while “Both answers are acceptable” means the two answers are acceptable.
What is the difference between neither and none?
Neither normally refers specifically to two people or things and means not one of them. None can refer to a group of two or more and means not any of them.
Is “I don’t like neither” grammatically correct?
In standard English, avoid this double-negative construction. Use “I don’t like either” or “I like neither” instead.
Which is correct: “Neither answer is” or “Neither answer are”?
The standard form is “Neither answer is.” When neither directly modifies a singular noun, a singular verb is normally used: “Neither answer is correct.”
Which is correct: “Either option is” or “Either option are”?
The standard form is “Either option is.” Because either refers to one of two options, a singular noun and singular verb are normally used in this construction.
Can “either” mean “also”?
Yes. In negative sentences, either can mean “also.” For example, “I don’t understand it either” means “I also don’t understand it.”
Conclusion
The difference between either vs neither becomes much easier once you remember their basic meanings. Either refers to one of two choices or possibilities, while neither means not one and not the other.
Use either…or to present alternatives:
You can either stay here or come with us.
Use neither…nor to exclude both alternatives:
You can choose neither the red one nor the blue one.
Also remember that either can appear in negative sentences:
I don’t want either option.
And neither already carries a negative meaning:
I want neither option.
For standard US English, pay attention to subject-verb agreement, especially with constructions such as neither answer is and either option is.
Once you connect either with “one of two” and neither with “not one or the other,” choosing the correct word becomes much easier.
Quick Reference
- Either = one of two
- Neither = not one and not the other
- Either…or = one alternative or the other
- Neither…nor = not this alternative and not that alternative
- Either of = one of two
- Neither of = not one of two
- Both = the two together
- None = no members of a group, often three or more
- Any = one or more choices from a group, often three or more
The key is to focus on whether you are allowing one of two choices or rejecting both choices. That distinction will help you use either and neither correctly in everyday speech and writing.
