والعام: كل لفظ ينتظم جمعاً من الأفراد
A general expression is one that encompasses a plurality of individuals.
The verb yantaẓim conveys the inclusion of individuals within the expression's scope. The statement is not limited to a single specified person; the term can range over many.
Generality does not depend on how many letters or words an expression contains. The decisive matter is whether its denotation identifies a determinate concept individually or encompasses multiple members.
