أما الجزئي: فهو ما يمنع نفس تصوره عن صدقه على كثيرين
A particular is a concept whose very conception prevents its applicability to many individuals.
The phrase “its very conception” is decisive. It does not merely mean that we happen to encounter one instance in the world. Rather, grasping the intended meaning already prevents its simultaneous identification with distinct individuals.
For example, the identity of this specific person, Zayd, cannot in the same respect be the identity of another distinct person, ʿAmr. It is therefore a real particular.
