«وأما المنفصلة: فهي التي حكم فيها بالتنافي بين شيئين في موجبة، وسلب التنافي بينهما في سالبة»
A disjunctive conditional affirms incompatibility between two things in its affirmative form, and denies that incompatibility in its negative form.
Incompatibility (tanāfī) concerns whether two propositions may both be true, both false, or neither, under a specified respect. Different restrictions on these possibilities produce different kinds of disjunction.
For “This number is either even or odd,” two alternative claims are presented. The word “or” alone does not establish the precise truth–falsity relation.
