Predicates, philosophy, logic: predicates are symbols that can stand in logical formulas for properties. In fact, not every predicate stands for a property, since it has contradictory predicates, but no contradictory properties. For example, one can think of a predicate "squaround" for "square and round", that is, two properties that exclude each other. One can then truthfully say "Nothing is squaround". There are therefore more predicates than properties. See also round square, scheme characters, quantification, 2nd level logic, predication, attributes, adjectives.

David M. Armstrong on Predicates - Dictionary of Arguments

III 114
Predicate/property/Armstrong/(s): a predicate is not a property. - The predicate "to be a mass" is permitted, but no real property.
Armstrong: something specific falls under "determinable". (>determinates/determinables).
Problem: properties of properties: regress possible. - Then there are intermediates: as between e.g. redness and a certain hue. - ArmstrongVs: we should not multiply properties like those for which they are only a shadow of predicates or be constituted by classes of particulars. >Regress.
