Is
everyone singular or plural? Most people have no trouble pairing it correctly with a singular verb:
(1) Everyone
likes the cake.
(2) Everyone
has a role to play.
Hardly would any competent speaker use a plural verb for
everyone:
(3) *Everyone
like the cake.
(4) *Everyone
have a role to play.
And that's all well and good. The indefinite pronoun
everyone is singular and there's little confusion or disagreement about that.
Trouble starts when a pronoun is involved:
(5) Has everyone finished
their drinks?
(Longman Dictionary of Contemporary English)
(6) Everyone tells us that
they enjoyed the movie.
If
everyone is singular, why do even competent speakers of English use the plural
their or
they to refer to it? Is any grammar rule broken when we use
their or
they for
everyone?
Here is what Quirk et al. (221) wrote about
they in relation to indefinite pronouns:
The pronoun they is commonly used as a 3rd person singular pronoun that is neutral between masculine and feminine. It is a convenient means of avoiding the dilemma of whether to use the he or she form. At one time restricted to informal usage, it is now increasingly accepted even in formal usage, especially in AmE.
Rather than use he in the unmarked sense or the clumsy he or she, many prefer to seek gender impartiality by using a plural form where possible in reference to the indefinite pronouns everyone, everybody, someone, somebody, anyone, anybody, no one, nobody:
Everyone thinks they have the answer. [1]
Has anybody brought their camera? [2]
...
In formal English, the tendency has been to use he as the unmarked form when the gender is not determined. The formal equivalent of [1], though increasingly ignored, is therefore:
Everyone thinks he has the answer. [1a]
So if you were ever doubtful, you can now set your mind at ease and use
they or
their to refer to
everyone.
However, because
everyone and
they are generally understood as singular and plural respectively, mixing them can sometimes raise eyebrows.
In formal writings, therefore, the more careful writers prefer to use
his or the less sexist
his or her:
(7) Has everyone finished his drink?
(8) Has everyone finished his or her drink?
To avoid the problematic
everyone and
they, a common approach is to rewrite by making the subject plural:
(9) All of them tell us that they enjoyed the movie.
