كَتَقْدِيمِ الْخَبَرِ عَلَى الْمُبْتَدَإِ
For example, advancing the predicate before the subject.
The position of a definite predicate can focus the attribution on one specified subject. Expressions such as “Zayd is the one standing” and “the one standing is Zayd” must be analyzed by identifying what is restricted and to what it is restricted, not merely by noting definiteness.
Fronting can carry restriction, but context still matters. It is unsound to assign every inversion one fixed direction of qasr.
