Otherwise signals a conditional consequence: it introduces a hypothetical outcome that follows from the absence of a prior condition or action. It functions to clarify that a particular result would occur only if the stated condition is not met, thereby establishing a logical dependency between a premise and its alternative outcome. Use it when you want to emphasize what would happen in the absence of a stated action, rule, or circumstance.
