Category talk:Precoordinated Concept
"A concept, which is defined in terms of two-or-more other concepts, within a terminology set, and which has been assigned a unique identifier."
Pre-coordination does not require explicit structure within the system. "Arm" is precoordinated, whether or not it is fully defined (e.g., as "extremity" + "has anteriority" + "upper").
