# Domain (Syntax)

From Glottopedia

**Domain** is in checking theory the domain of a head A is the set of nodes contained in Max(A) that are distinct from and do not contain A.

### Example

in (i) the domain of X (a head) is the set of nodes UP, ZP, WP, YP, and H and whatever these categories dominate. XP_{1}, XP_{2}, X', X_{1} and X_{2} are not included in the domain of X, since each of these nodes contain X, and X is not distinct from X.

XP_{1}/\ / \ UP XP_{2}/\ / \ ZP_{1}X' /\ /\ / \ / \ WP ZP_{2}X_{1}YP /\ / \ H X_{2}
