فإن كانت الشرطية متصلة فاستثناء عين المقدم ينتج عين التالي
If the conditional is connected, asserting the very antecedent yields the very consequent.

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.
