A sign may frequently accompany a property without forming a perfectly reversible relation. Tall stature can make a long sword strap appropriate, but a long strap need not always belong to a tall person.
Therefore, “concomitant to what it implies” and the reverse direction cannot be used as a mechanically universal test. A more reliable analysis attends to literal meaning, intended meaning, conventional connection, and contextual indication.
Allowing an association to be considered from two directions does not erase the distinction between kināyah and majāz: the status of literal intention remains essential.
