boundary
Where territories meet
A boundary is a line or limit that separates one area from another—between countries, properties, or zones.
The word extends to abstract limits: personal boundaries, the boundaries of acceptable behavior.
To push or test boundaries is to challenge established limits.
In cricket, a boundary is a hit that reaches the edge of the field, scoring four or six runs.
