ومنها الاستعارة التهكمية والتمليحية
Ironical and wittily inverted metaphors are included under the opposing class.
Tahakkum is a deliberately derisive use of an expression whose ordinary sense would commend or promise something, while the discourse intends rebuke, threat, or degradation. The contrast is rhetorical: a positive-looking word can be made to serve a negative purpose.
Simply placing antonyms together is not sufficient. The larger context or tone must show that the speaker is using the mismatch intentionally. That dependence on opposition explains its place in the category of ʿinādiyyah.
