Analyse a subject qualifier by first identifying the subject and what the listener already knows. Then ask whether the epithet unpacks a meaning, distinguishes a known individual, narrows a class, conveys praise or blame, or reinforces an implied feature.
Uncovering: الجسم الطويل العريض العميق — reveals conceptual content.
Clarification: زيد التاجر — resolves uncertainty about a named person.
Restriction: رجل صالح — narrows possible instances.
Praise/blame: زيد العالم / زيد الجاهل — contextually evaluates.
Reinforcement: أمس الدابر — stresses what is already implied.
These are genuine functions of qualification, but the principal intended function must be inferred from context, not the grammar alone.
