Etymology
The word 'implausibility' is built upon the Latin verb 'plaudere', which meant "to strike, clap, or applaud." From this concrete action, the derived adjective 'plausibilis' came to mean "deserving applause, acceptable, or believable." The negative prefix 'im-' (a form of 'in-' before 'p') was attached to form 'implausibilis', meaning "not deserving approval or belief." The English noun 'implausibility' was formed by adding the abstract noun suffix '-ity' to this negative adjective, completing the journey from the physical act of clapping to the modern abstract concept of something being unconvincing or hard to accept as true.
