Sophistical
Sophistical is an adjective meaning relating to sophists or their rhetoric, or describing arguments that are superficially plausible yet deceptive or fallacious. The term is derived from Latin sophisticus, itself from Greek sophistikos, from sophistēs, a maker of wisdom or an expert in argument. In ancient Greece, sophists were professional teachers of rhetoric and disputation; they were valued for eloquence and practical instruction, but criticized by philosophers for prioritizing persuasive effect over truth.
In modern usage, sophistical often carries a negative connotation. It is applied to reasoning or discourse
