وَأَمَّا غَيْرُ الْهَمْزَةِ فَيَجِيءُ لِلتَّقْرِيرِ وَالْإِنْكَارِ
Other interrogative expressions may also be used for elicited acknowledgment and denial.
Taqrīr and inkār are not exclusive to hamza; the passage also assigns them to other interrogative particles. Yet the detailed device of placing a particular sentence constituent after hamza cannot simply be copied wholesale to every other interrogative.
Two constructions can share the purpose of denial while differing in syntax and the specific constituent placed in focus. Analyses should therefore distinguish the broad rhetorical purpose from the grammatical mechanism realizing it.
