Give yourself a round of applause if you recognize the similarity between today's featured word and a pair of familiar words. (There's a hint in the first half of the previous sentence, as well as in the first sense of the definition.) "Plaudit" was borrowed into English in the early 17th century from a form of the Latin verb "plaudere," meaning "to applaud." "Plaudere" is, of course, also the ancestor of "applaud" and "applause," as well as of "explode," "plausible," and the now archaic "displode" (a synonym of "explode").
