FunctionKey question
Distinction (tamyīz)Is the following expression a predicate or only a modifier?
Emphasis (taʾkīd)Is an existing attribution being reinforced?
Restriction (takhṣīṣ/qaṣr)Is this predicate attributed to a particular subject exclusively?
These functions illustrate the link between syntax and rhetoric. Distinction clarifies sentence structure; emphasis and restriction modify how the hearer interprets the predication.
One function may dominate in a given context. It is not sound to force every possible effect into every instance.
