Linguistic Origin & Historical Etymology

Derived from the Latin 'impllausibilis', combining the negative prefix 'in-' (not) and 'plaudere' (to applaud or strike). Entering English in the early 17th century, it originally meant not deserving applause, but evolved to describe an argument, statement, or story that fails to appear reasonable or believable.
