Either, neither, both

"We have both red and white wine - which would you like?"   "Neither, thanks. I'd prefer a beer if you have any." 

Either, neither and both are quantifiers which we use to talk about two things or people.


There are lots of different structures. Here are some of them:

 

 

 

 

 

Either

 

+ singular noun

 

without a noun

 

+ two singular nouns

 

+ of + plural noun

 

 

Either day is OK for me.

 

Either is OK for me.

 

Either Monday or Wednesday is OK for me.

 

Either of those days is OK for me.

 

 

Neither

 

+ singular noun

 

without a noun

 

+ two singular nouns

 

+ of + plural noun

 

 

Neither day is OK for me.

 

Neither is OK for me.

 

Neither Monday nor Wednesday is OK for me.

 

Neither of those days is OK for me.

 

Both

 

+ plural noun

 

without a noun

 

+ two singular nouns

 

+ of + plural noun

 

after a noun

 

Both days are OK for me.

 

Both are OK for me.

 

Both Monday and Wednesday are OK for me.

 

Both of those days are OK for me. 

 

Those days are both OK for me.

 

 

 

Note that with 'of', we need to use 'the', a demonstrative, a possessive adjective or a pronoun.

 

Are either of the candidates suitable?

I've seen both of these films.

Neither of my children likes vegetables.       Neither of them likes vegetables

 

 

We can use both in this way without 'of' but it is necessary for either and neither:

 

Both (of) her parents are teachers.  Image

Neither of her parents are teachers.    Image       Neither her parents are teachers. Image

Are either of her parents teachers? Image

Note that 


1.    With either and neither we can use a singular or plural verb. In conversation, both are acceptable:


"Have either of you seen my keys?"


but a singular verb is preferred in formal written English:


Neither of our sales targets has been reached.


2.    When there is more than one noun, the choice of verb depends on whether the first or second person or thing mentioned is singular or plural:



 

 

When the second noun is singular - singular verb preferred but plural verb acceptable in conversation.

 

 

Either the sales manager or the director is going to attend the conference.

 

 

When the second noun is plural - plural verb.

 

Either the director or the sales managers are going to attend the conference.

 

 

When the second noun is singular but the first is plural - a singular or plural verb.

 

Either the sales managers or the director is/are going to attend the conference.

 

 


 


As well as nouns, we can use either, neither or both to talk about other things, including adjectives and actions:

 

This car is available in either red or blue.

We can either drive or go by train.

She's neither helpful nor polite.

She can both sing and dance.

  

We use 'either...or...'; 'neither...nor...' and 'both...and...' to include two people or things in a sentence or clause:

 

She has either a brother or a sister - I can't remember.

She has neither a brother nor a sister.

She has both a brother and a sister.

 

 

These structures can also be used with verbs:

 

I'll either reply to my emails this afternoon or do some research; I don't have time for both.

She neither smokes nor drinks.

She both smokes and drinks.
