Today the word plausible usually means "reasonable" or "believable," but it once held the meanings "worthy of being applauded" and "approving." It comes to us from the Latin adjective plausibilis ("worthy of applause"), which in turn derives from the verb plaudere, meaning "to applaud or clap." Other plaudere descendants in English include applaud, plaudit (the earliest meaning of which was "a round of applause"), and explode (from Latin explodere, meaning "to drive off the stage by clapping").
