ومنها: ما يقع بسبب تقدم الروابط وتأخرها عن السلوب
Another mistake arises from the relative positions of copulas and negations.
The text compares formulations such as زيد ليس هو بقائم and زيد هو ليس بقائم. Their analysis depends on whether negation denies the predication itself or enters into the expression being predicated.
The essential question is whether negation has scope over the proposition or forms part of a negated predicate. Failing to separate these can confuse negative, negative-term, and modal propositions.
