  • All concepts except the 
    Gloss
    troot concept
     have at least one proximal primitive supertype concept. In many cases this is a top level hierarchy concept. However, in some case one or more intermediate primitive supertypes may exist between the top level concept and a defined concept.
  • A concept's proximal primitive supertypes represent aspects of the meaning of that concept that are not formally defined by other
    Gloss
    taxioms
    . 
  • The chapter on  Proximal primitive modeling in the  DOCEG explains the role of proximal primitive supertypes in modeling concepts.

 the concepts C, D, E and F have a single proximal primitive supertypesupertype B. Concept oncept A is also primitive, but it is a supertype of B so it is not a proximal primitive supertype of these concepts. Similarly concepts concepts H, J and N have a single proximal primitive supertype G. Concepts L and M have a single proximal primitive supertypeI. Note that G is not a proximal primitive supertype for these concepts because it is a supertype of concept I. In this hierarchy only concept P has more than one proximal primitive supertypes. The proximal primitive supertypes of concept P are concepts K and I as neither of these concepts is a supertype of the other.
