One response allows that even a minimal aptness may motivate naming an imagined form after a familiar form. The resemblance between hypothetical and actual claws can thus explain a figurative application.
But another issue remains: if the imagined judgment does not assert a physical fact, how exactly does it relate to real anatomy? Some accounts call the act imaginative predication, while others frame it as a verbal metaphor.
The disagreement concerns not merely whether a label is apt, but the kind of predication being made.
