Dirimens copulatio presents two opposed possibilities in a parallel structure and then denies that either provides an answer. A poet might say, “Neither in the crowded square nor in the empty field could I forget you.” The device gives shape to inner conflict while showing that simple alternatives fail. It can heighten a sense of entrapment, complexity, or emotional persistence, especially when a speaker finds no refuge in either extreme.

Dirimens copulatio presents two opposed choices and then dismisses both as inadequate, harmful, or false. The pattern often sounds like “not this, nor that,” pushing readers toward a third possibility or a more complex conclusion. It is useful in argumentative poetry and political rhetoric. Compare antithesis, which balances contrasts without necessarily rejecting them.
