«ويسمى غير المعدولة في الموجبة بالمحصلة، وفي السالبة بالبسيطة»
A non-metathetic proposition is called muḥaṣṣalah when affirmative and basīṭah when negative.
Affirmative muḥaṣṣalah: “Zayd is learned” — an affirmative judgment, with no negative particle built into either term.
Negative basīṭah: “Zayd is not learned” — the link is denied, while the predicate learned is an unnegated term.
The names contrast with maʿdūlah. Affirmative/negative state the quality of the judgment, while metathetic/non-metathetic describe whether a negative forms part of a term.
