Headscratcher for THEIR
It's easy to mix up their, they're and there. Their and they're are both forms of the third person pronoun. Their means “belonging to them.”They're means “they are.”There is not related in meaning but means “in that place.” Here is a sentence that uses all three: They're on their way there.
