الْقَصْرُ
Restricting one element to another through a recognized form.
Direction: attribute-to-subject or subject-to-attribute.
Scope: actual real, rhetorically claimed real, or relative.
Listener’s stance: within relative qasr, ifrād, qalb, or taʿyīn.
This taxonomy is the conceptual foundation for the next discussion: how the Arabic language produces qasr through coordination, negation and exception, and other constructions. Those methods must be analyzed with the same discipline about direction and scope.
