The terms imaginative and realizable do not merely describe grammatical form. An imaginative account assigns an attribute meaningful within the picture but not literally possessed by the target. A realizable account identifies a quality that can genuinely characterize the subject.
Death has no physical claws, yet its severity and inescapable power can be meaningfully described. Thus an imagined bodily attribute and the real condition expressed through it belong to different analytical levels.
The issue is not whether imaginary anatomy is a literal report. It is which genuine quality is conveyed through which imagined device.
