Is “their” a common word?

What is the difference between their, there, and they're?
"Their" is a possessive determiner meaning belonging to them, as in "their house." "There" refers to a place ("put it there"), and "they're" is the contraction of "they are." Because all three sound identical, they are among the most commonly confused words in English writing.
Can their refer to just one person?
Yes. "Their" is widely used as a singular possessive when a person's gender is unknown, irrelevant, or non-binary, as in "someone left their umbrella." This singular use is accepted by major dictionaries and style guides, though some very formal writing still prefers "his or her."
What is the difference between their and theirs?
"Their" is a determiner and must be followed by a noun ("their car"), while "theirs" is a possessive pronoun that stands alone ("the car is theirs"). Neither word ever takes an apostrophe — "their's" is always incorrect.
Is it spelled their or thier?
The correct spelling is always "their," with e before i. "Their" is one of the common exceptions to the "i before e except after c" rule, which is why "thier" is such a frequent misspelling.
