Did you know?

Theatergoers in ancient Rome could be noisy in showing both their enjoyment and their dislike of a performance. One of the ways they made noise was by clapping their hands loudly. The Latin verb plaudere meant “to make a noise by loud clapping.” When Romans were showing their approval of a performance, the word used was applaudere, from which we get our English word applaud. When Romans did not like a performance, they often drove the performer from the stage by loud claps. The word for this was explodere or explaudere, from the prefix ex-, meaning “out, away,” and plaudere. From this word we get our English word explode. At first, explode meant “to drive from the stage by a noisy expression of dislike,” but this sense has all but disappeared.

Etymology

from Latin explaudere "to drive off the stage by clapping," from ex- "out, away" and plaudere "to clap" — related to applaud, plaudit, plausible see Word History at plausible

Word Origin
Theatergoers in ancient Rome could be noisy in showing both their enjoyment and their dislike of a performance. One of the ways they made noise was by clapping their hands loudly. The Latin verb plaudere meant "to make a noise by loud clapping." When the Romans were showing their approval of a performance, the word used was applaudere, from which we get our English word applaud. When the Romans did not like a performance, they often drove the performer from the stage by loud claps. The word for this was explaudere, from the prefix ex-, meaning "out, away," and plaudere. It is from this word that we get our English word explode. In the beginning, the English word explode had the meaning "to drive from the stage by a noisy expression of dislike." But this sense has all but disappeared. Other meanings that have either the idea of disapproval or the idea of violent noise have since come into wide use.
