The principal topics of ʿilm al-bayān are now complete: forms of signification, simile, literal and figurative usage, metaphor, and kināyah. The common problem has been how meaning is conveyed and inferred.
The next discipline is ʿilm al-badīʿ, which examines embellishments of sense and wording after appropriateness and intelligible indication have been addressed.
The lasting analytical priority is to understand meaning, attribution, contextual clues, and occasion before evaluating verbal or semantic ornament.
