 For related reasons, most workers reject any rigid–nonrigid distinction for purely predicative expressions. That would include ‘green’ and ‘honeybee’, on a nominalist’s approach according to which there is no property to designate and on some realist approaches, too, such as a Fregean approach according to which properties exist but cannot be named. Other still-more widely accepted candidates for purely predicative status would be the predicates ‘is green’, and ‘is a honeybee’.
