فإن كانت الشرطية متصلة فاستثناء عين المقدم ينتج عين التالي
If the conditional is connected, asserting the very antecedent yields the very consequent.
Form:
If A, then B.
But A.
Therefore B.
The conditional states that B follows from A, while the second premise establishes A. Therefore B follows. The inference is valid because of its form, not because of any particular wording.
