The final discussion notes a useful structural contrast: with negation and exception, the element retained by restriction commonly follows illā (إلا), whereas with innamā (إنما) the focus must be interpreted with attention to constituent order, often involving a later element.
For example, “mā ḍaraba illā ʿAmran Zayd” makes the location of “ʿAmran” important: the striking is restricted to that object. In “innamā ḍaraba Zaydun ʿAmran,” syntax and context direct attention to the relation of the action to its object.
All four methods can express specification, but word order, explicit negation, and the syntactic role of an exception establish its direction. This care with structure prepares for the next chapter on non-declarative expression (الإنشاء).
