+# Personhood
+
+**Status:** provisional  
+**See also:** H2, RQ2, APE in `Terminology.md`
+
+## Working definition
+
+**Personhood** describes the extent to which an entity exhibits properties commonly
+associated with persons. Multidimensional, not binary.
+
+Unless explicitly qualified, Soul Frame uses personhood **descriptively**, not as
+moral or legal status.
+
+## Distinctions to maintain
+
+| Kind | Focus |
+|---|---|
+| Descriptive personhood | Person-like capabilities and characteristics |
+| Social personhood | Recognition and treatment as a social counterpart |
+| Moral personhood | Status giving rise to moral consideration |
+| Legal personhood | Status created or recognized by legal systems |
+
+## Relation to Being
+
+Personhood concerns qualities exhibited.  
+Beinghood concerns whether qualities cohere into an identifiable, persistent system
+recognized as an individual counterpart.
