كاستعارة اسم المعدوم للموجود لعدم غنائه
For instance, applying “nonexistent” to something that exists because it affords no benefit.
The external reality is that the person or thing exists. The figurative assertion treats it as nonexistent for a specific purpose: emphasizing the absence of practical use. Simply saying “he is absent” does not establish this kind of metaphor; the person might literally be away.
An opposing metaphor deliberately exploits the contrast between existing and nonexistent, rather than making a nonsensical metaphysical claim. The original state, the denied benefit, and the contextual indication must all be identified.
