In the Snomed CT User Guide Primitive is described as follows:

An expression, which may be just a single concept code, is primitive when its logic definition does not sufficiently express its meaning so that its subtypes can be computably recognized. A concept code's logic definition is made up of its defining relationships to other concept codes, via attributes and | is a | relationships. Primitive concept codes also do not have the defining relationships that would be needed to computably distinguish them from their parent or sibling concepts. For example, if the Concept "Red sports car" is defined as [is a=car] + [ color =red] this is Primitive but the same definition applied to the Concept "Red car" is sufficiently defined.
