Word
domain
Meanings
a particular area of knowledge, activity, or influence
a territory or area controlled or ruled by someone or something
the main part of an internet address (for example, the part that ends in .com, .org, or a country code)
Definition
A domain is an area of knowledge, activity, or authority, or a specific website address ending such as .com.
A domain can mean a particular field or sphere, such as science, art, or someone’s area of responsibility. It can also refer to territory or land controlled by a person or group. In computing, a domain is the main part of an internet address and can also mean a network that shares rules for access and security. The context usually makes clear which meaning is intended.
Examples
- Her domain is computational linguistics, and she’s known for explaining complex ideas with unusual clarity.

- Their domain stretched from the mountains to the coast, linking dozens of villages by trade routes.
- I bought the domain years ago, but I only built the site once I had a clear editorial plan.
Common mistake
Learners often confuse domain with dominion and use it to mean “power” rather than “a field” or “a territory” (or an internet address).
