You Can Believe This History of Plausible

Put your hands together for plausible, a word with a sonorous history. Today the word usually means "reasonable" or "believable," but its origins lie in the sensory realm, rather than that of the mind. In fact, plausible comes to us from the Latin adjective plausibilis, meaning "worthy of applause," which in turn derives from the verb plaudere, meaning "to applaud or clap." Other plaudere words include applaud, plaudit (the earliest meaning of which was "a round of applause"), and explode (from the Latin explodere, meaning "to drive off the stage by clapping"). Will the evolution of plaudere continue? Quite plausibly, and to that we say "Bravo."

In our solar system, the biggest moon is Jupiter's Ganymede, which has a mass only 2.5 percent that of Earth—too small to easily hang on to an Earth-like atmosphere.

from Latin plausibilis "deserving applause, pleasing," from plausus, past participle of plaudere "to clap" — related to applaud, explode, plaudit see Word History at explode

Word Origin
A plausible explanation is one that sounds as if it could be true. Such an explanation is not usually greeted with applause, but the origin of plausible suggests that it might be. Plausible comes from the Latin word plausibilis, meaning "worthy of applause." The first use of plausible in English was to describe a person or thing that deserved special praise. That use is now obsolete. To call something plausible now is to praise it only slightly, if at all.
