Understanding the Basic Meaning of “Their”
Before we compare their life vs their lives, we must understand the word their.
Their is a possessive adjective. It shows ownership or connection. It usually refers to more than one person, but it can also refer to one person when the gender is unknown or not important.
Examples:
- The students forgot their books.
- Someone left their phone on the table.
In both cases, their shows that something belongs to someone. The key point is that their does not decide whether the noun is singular or plural. The noun decides that.
What Does “Their Life” Mean?
Their life uses a singular noun: life. This phrase talks about life as one complete thing. It often focuses on the overall experience, story, or condition of a person or group.
When “Their Life” Is Correct

- You describe one shared experience.
- You refer to life in a general or abstract way.
Examples:
- They want to improve their life.

In these sentences, life is seen as one journey, not many separate parts.
What Does “Their Lives” Mean?
