Domain

A particular field of thought, activity, or interest, especially one over which someone has control, influence, or rights.

In Domain-Driven Design (DDD), a “domain” is the specific subject area or sphere of knowledge that an application is built to serve, encompassing all the related business logic, rules, and processes. It’s not about the technology, but about the core business problem the software is trying to solve
