A more thorough explanation:

Definition: Exterritorial refers to something that is outside of a particular territory or jurisdiction. It is often used interchangeably with the term extraterritorial.

Example: Diplomatic embassies are considered exterritorial, meaning they are not subject to the laws of the country they are located in. For example, the United States Embassy in London is considered exterritorial, and therefore, the British police cannot enter the embassy without permission.

Explanation: The example illustrates how exterritorial refers to something that is outside of a particular territory or jurisdiction. In this case, the embassy is considered exterritorial because it is not subject to the laws of the country it is located in. This means that the embassy is essentially its own territory and is governed by the laws of the country it represents.
