A more thorough explanation:

Definition: To have legal title or right to something. Mere possession is not ownership.

Example 1: John owns a car. He has the legal right to use it, sell it, or give it away.

Example 2: Sarah found a lost wallet on the street. She has possession of it, but she does not own it. The rightful owner has the legal title and right to the contents of the wallet.

The examples illustrate that ownership is not just about having something in your possession. It is about having the legal right to use, sell, or give away something. Without legal title or right, possession alone does not constitute ownership.
