الِاسْتِفْهَامُ بِبَاقِي الْأَلْفَاظِ
Interrogation with the other interrogative expressions.
The central result of the section is that the expressions have different primary objects of inquiry. But interrogative form does not always mean the speaker genuinely seeks an answer. It can also communicate reproach, amazement, denial or magnification.
The next subsection, 'Use of interrogative expressions for other than interrogation,' examines those transferred purposes. Understanding the primary meanings first makes it possible to distinguish literal questions from their rhetorical extensions.
