وهذا ظهر أن ترك الحقيقة لا يوجب المصير إلى المجاز
Leaving the full literal range does not always require figurative meaning.
بل جاز أن تثبت به الحقيقة القاصرة، ومثاله: تقييد العام بالبعض
A restricted literal application may remain; one example is confining general wording to some of its instances.
This is a technical distinction: when custom restricts an otherwise broad expression, the resulting meaning need not be pure metaphor. The expression may be used within its literal category, though only for a delimited subset.
A *complete* literal application covers the broader lexical field. A *restricted* application keeps the relevant literal relation but specifies which members matter.
Distinguishing specification from figurative transfer prevents us from labeling every narrowing of reference as metaphor.
