1. Answer, rejoinder, reply, response, retort all mean words used to meet a question, remark, charge, etc. An answer is a return remark: an answer giving the desired information. A rejoinder is a quick, usually clever answer or remark made in reply to another's comment, not to a question. Reply usually refers to a direct or point-by-point response to a suggestion, proposal, question, or the like: a reply to a letter. A response often suggests an answer to an appeal, exhortation, etc., or an expected or fixed reply: a response to inquiry; a response in a church service. A retort implies a keen, prompt answer, especially one that turns a remark upon the person who made it: a sharp retort.
