ludicrous
UK: ˈluːdɪkrəs | US: ˈluːdɪkrəs
adj. so absurd or ridiculous as to be laughable
adj. wildly unreasonable or improbable
Derived from Latin ludicrum ("stage play" or "mockery"), ludicrous originally described theatrical exaggeration. By the 17th century, it evolved to mean "unreasonably exaggerated" in English, capturing the leap from playful performance to outright absurdity. The root lud- (play) survives in words like ludic (playful) and allude (to play with words indirectly).
