• Synonyms Argue, Dispute, Debate, Discuss, plead, expostulate, remonstrate. To argue is to defend one's opinion, or to exhibit reasons or proofs in favor of some assertion or principle; it implies a process of detailed proof by one or more persons. To dispute may be to call in question the statements or arguments of an opposing party: as, to dispute about an award. It often means the alternate giving of reasons, especially by two persons. It is often applied to mere bickering, and is in general less dignified than the other words. To debate is to interchange arguments in a somewhat formal manner, as in debating societies and legislative bodies. To discuss is, by derivation, to shake or knock a subject to pieces in order to find the truth, or the best thing to be done. A debate, therefore, may be viewed as a discussion, or a discussion as a debate. Strictly, a discussion is an amicable presentation of opinions, not limited, like the others, to affirmative and negative sides of a proposition, and with the expectation on the part of all that the conclusion will be the adoption of no one person's opinion or plan unmodified. To argue a point, to dispute a position, to dispute with a neighbor, to debate a motion, to discuss a subject or a plan.
