their

Belonging to them

We pronounce their in the same way as there, but the pair behave completely differently in sentences and can never properly substitute for each other.

Their‘s only function is to be a possessive for the third person plural of his, her, and its, or as the possessive form of they: They left with their children about an hour ago.

When their is used after a singular pronoun it is usually to avoid having to say his or her.

Most authorities today find this usage acceptable: Everyone can drive in their own cars.

Their is also used for a single person of unknown gender: Did anyone leave their phone in the locker room?
