Can they be used as an indefinite subject?: Usage Guide

They used as an indefinite subject (sense 2) is sometimes objected to on the grounds that it does not have an antecedent. Not every pronoun requires an antecedent, however. The indefinite they is used in all varieties of contexts and is standard.

Can they, their, them, and themselves be used as singular pronouns?: Usage Guide

They, their, them, themselves: English lacks a common-gender third person singular pronoun that can be used to refer to indefinite pronouns (such as everyone, anyone, someone). Writers and speakers have supplied this lack by using the plural pronouns.

and every one to rest themselves betake William Shakespeare
I would have everybody marry if they can do it properly Jane Austen
it is too hideous for anyone in their senses to buy W. H. Auden

The plural pronouns have also been put to use as pronouns of indefinite number to refer to singular nouns that stand for many persons.

'tis meet that some more audience than a mother, since nature makes them partial, should o'erhear the speech William Shakespeare
a person can't help their birth W. M. Thackeray
no man goes to battle to be killed.—But they do get killed G. B. Shaw

The use of they, their, them, and themselves as pronouns of indefinite gender and indefinite number is well established in speech and writing, even in literary and formal contexts. In recent years, these pronouns have also been adopted by individuals whose gender identity is nonbinary, as illustrated in sense 3d of they.

Did you know?

There vs. They're vs. Their

There, they're, and their: they sound the same but have different meanings and keeping them straight can be very tricky.

We'll start with there. It has the word here in it, which can help remind us that this particular word is often about location:

There it is.

Put it there.

Stay there.

We'll be there soon.

It's about location in the more abstract sense too:

There you go.

There is where we disagree.

Friends who are always there for you.

It's also the one to use as the first word in sentences that have the subject after the verb:

There goes the bus.

And it's the one used with is and are at the beginning of sentences and questions:

There are plenty available.

Is there a hotel in the town?

The other two are trickier because they both have the idea of the plural in them. Both are connected to the idea of "them."

They're means "they are":

They're (=they are) funny people.

They're (=they are) the cutest puppies ever.

It can be used of non-living things too:

They're (=they are) both really good books.

They're (=they are) two of our biggest problems.

The last of this trio, their, is the possessive form of they, so it has to do with what belongs to, relates to, or is made or done by certain people, animals, or things:

It's their house.

We're their neighbors.

The trees are losing their leaves.

And there you go. They're not an easy group of words, but with practice we know you can master their distinctions.
