Is 'Either' Singular or Plural?

by Craig Shrives

This Page Includes...

"Either" and "neither" are singular.

Treat "either" and "neither" as singular. For example:
  • Either is acceptable. correct tick
  • Neither of the boys is trying. correct tick

"Either/or" and "neither/nor" can be singular or plural.

When "or" or "nor" joins two elements, use a singular verb if both elements are singular. However, if one of the elements is plural, use a plural verb. In these examples, the elements are shaded.
  • Shortbread or cake is on offer. correct tick
  • ("Shortbread" and "cake" are singular.)
  • Chocolates or cake are on offer. correct tick
  • ("Chocolates" is plural.)
Be mindful though that many writers follow the Proximity Rule. This states that the element nearest the verb governs it. For example:
  • Chocolates or cake is on offer. correct tick
  • (Using the Proximity Rule, the verb becomes singular because "cake," which is the nearest element to the verb, is singular.)

More about Either and Neither

"Either" and "neither" are singular concepts. (They contrast with the word "both.")

The word "either" can be a pronoun or a determiner. "Either" means "one or the other of two things." It attracts a singular verb.

The word "neither" can also be a pronoun or a determiner. It means "not one nor the other of two things, i.e., not either." It also attracts a singular verb.

Examples Showing "Either" and "Neither" As Singular

Here are some examples showing "either" and "neither" as singular concepts:
  • Either car is available. correct tick
  • (Here, "either" is a determiner modifying "car." The term "either car" is singular.)
  • Either is available. correct tick
  • (Here, "either" is a pronoun. It is singular.)

  • Neither man is suitable. correct tick
  • (Here, "neither" is a determiner modifying "man." The term "neither man" is singular.)
  • Neither of the men is suitable. correct tick
  • (Here, "neither" is a pronoun. It is singular.)

Singular Verb with Singular Elements

If the pairings "either/or" (often the "either" is omitted) or "neither/nor" form part of the subject of a verb and both elements are singular, then the verb is singular too. For example:
  • Neither Mark nor Dawn is at the function. correct tick
  • (As "Mark" is singular and "Dawn" is singular, then "is" is correct. Using "are" would be wrong.)
  • Neither Dickens nor Thackeray was a panderer to the public taste. correct tick
  • (As "Dickens" is singular and "Thackeray" is singular, "was" is correct; i.e., "were" would be wrong.)
  • Either the clerk or the secretary has the keys to the Land Rover. correct tick
  • (As "clerk" is singular and "secretary" is singular, "has" is correct; i.e., "have" would be wrong.)
  • Either a mouse or a rat eats the cable at night. correct tick
  • Neither Simon nor Gary do as they are told. wrong cross
  • (As "Simon" is singular and "Gary" is singular, "do" is wrong. It should be "does." NB: Sometimes, you have to look further down the sentence too. This should be "does as he is told.")

Plural Verb with a Plural Element

If the pairings "either/or" or "neither/nor" form part of the subject and at least one of the elements is plural, then the verb must be plural too. For example:
  • Neither the lawyer nor the detectives are able to follow the sequence of events. correct tick
  • (Here, "lawyer" is singular, but "detectives" is plural. Therefore, "are" is correct.)
  • There were neither cakes nor ice-cream at the party. correct tick
  • Neither the firemen nor the policemen know him. correct tick
  • (Here, "knows," which is singular, would be wrong.)
  • Either the budgies or the cat has to go. wrong cross
  • (This should be "have" because "budgies" is plural.)

Correlative Conjunctions and the Elements

The pairings "either/or" and "neither/nor" are known as correlative conjunctions. The words that follow "either," "or," "neither," and "nor" are known as the elements.
  • Neither Mark nor Dawn is at the function.
  • (Here, the elements are shaded.)
  • Either tea and crumpets or cake are sufficient.
  • (Here, the elements are shaded.)
Be Brave with the Ruling

Sometimes, it may sound wrong to use the singular form of the verb. Be confident. If both elements are singular, use the singular form. For example:
  • Neither Jeremy nor Sarah was in the shop at the time of the theft. correct tick
  • (Here, "was" is correct. Using "were" would be wrong.)

Proximity Rule

Not all grammar conventions follow the ruling above. Under a ruling known as the "Proximity Rule," the verb is governed by the element nearest to it. For example:
  • Either crumpets or cake is sufficient.
  • (Under standard convention, this should read "are sufficient" because "crumpets" is plural. However, under the Proximity Rule, "cake" governs "is" because it is the nearest element.)
  • There was neither ice-cream nor chocolates at the party.
  • (Under standard convention, this should read "were" because "chocolates" is plural. However, under the Proximity Rule, "ice-cream" governs "was" because it is the nearest element.)

Satisfy Both Conventions!

If one of your elements is plural, put it nearest the verb. This will satisfy both conventions. For example:
  • Either cake or crumpets are sufficient. correct tick
  • (This satisfies both conventions.)
  • There were neither chocolates nor ice-cream at the party. correct tick
  • (This satisfies both conventions.)
