When should you use "their," "there," and "they're"?

The correct answer clarifies the distinct uses of "their," "there," and "they're." "Their" indicates possession, meaning that something belongs to them; for example, "Their car is parked outside" shows ownership. "There" refers to a location or existence, as in "The book is over there," indicating where something is situated. Finally, "they're" is a contraction for "they are," used in sentences like "They're going to the movies," where it replaces the longer form.

Each of these words serves a unique function in sentences, highlighting the importance of understanding context in language usage. Recognizing these differences is vital for effective communication, as using them interchangeably can lead to confusion or grammatical errors.
