Full Idea
It isn't clear what it is to name an abundant property. One might reify them, as akin to Fregean concepts, or it might be equivalent to a simple predication.
Clarification
'Abundant' properties can be odd groupings, or whimsical features
Gist of Idea
To name an abundant property is either a Fregean concept, or a simple predicate

A Reaction
'Fregean concepts' would make them functions that purely link things (hence relational?). One suspects that people who actually treat abundant properties as part of their ontology (Lewis) are confusing natural properties with predicates.
