Which of the following is NOT a characteristic of effective rhetoric?

Effective rhetoric is characterized by several key elements that enhance communication and persuasion. Clarity is crucial, as it ensures the intended message is understood without confusion. Persuasiveness is another essential aspect, as effective rhetoric aims to convince or influence an audience. Conciseness is important too; being brief yet informative helps maintain the audience's attention and emphasizes key points.

Ambiguity, on the other hand, undermines effective rhetoric. It introduces uncertainty and can lead to misinterpretations, making it difficult for the audience to grasp the speaker's or writer's intentions. Therefore, it is not a characteristic that would contribute positively to the effectiveness of rhetorical communication.
