وَيَخْتَصُّ بِالْمَنْقُوصِ، وَهُوَ مَا فِي آخِرِهِ يَاءٌ مَا قَبْلَهَا مَكْسُورٌ، كَـ«الْقَاضِي».
Translation: This pattern applies to the manqūṣ noun, which ends in a yāʾ preceded by a kasra, for example الْقَاضِي.
Both conditions matter: a final yāʾ and a kasra on the preceding letter. Merely ending in a written yāʾ is not enough.
