Muṭābaqah denotes the full conventional meaning, taḍammun one constituent within that meaning, and iltizām an associated implication recognized by the mind. These depend on the established signification of the expression and on the conceptual relation in question.
Without distinguishing a part of a meaning from a consequence of that meaning, one may misread the “necessary implication” central to kināyah. First ask whether the intended concept is included inside the word’s conventional meaning or inferred through a relation beyond it.
