What term describes the art of speaking or writing effectively?

The term that describes the art of speaking or writing effectively is rhetoric. Rhetoric encompasses various techniques and strategies used to persuade or impact an audience through language. It includes the study of how language can be used to communicate ideas, evoke emotions, and influence the thoughts and actions of others. This definition is fundamental to both speech and writing, making it essential for effective communication.

Mode refers to a particular way or manner in which something is expressed, but it does not specifically encompass the techniques of persuasion and effective communication like rhetoric does. Syllogism is a form of logical reasoning that involves drawing a conclusion from two premises; while it is a tool used within rhetoric, it does not define the broader art of effective communication itself. Fallacies are errors in reasoning that undermine the logic of an argument, but they are contrary to the principles of effective communication that rhetoric seeks to establish. Thus, rhetoric stands out as the central concept related to the art of effective speaking and writing.
