«القضية الموجبة وكذا السالبة تنقسمان إلى معدولة وغير معدولة»
Affirmative and likewise negative propositions divide into metathetic (maʿdūlah) and non-metathetic forms.
The new issue is not merely whether the entire judgment is affirmative or negative. Ask whether the negative particle is built into the subject term or predicate term, or instead negates the predicative connection itself.
In a maʿdūlah, negation forms part of the subject, predicate, or both; in a non-maʿdūlah, it does not. Counting a visible negative word is not enough.
