Etymology

Origin of ridiculous

First recorded in 1540–50; from Late Latin rīdiculōsus “laughable, droll,” equivalent to Latin rīdicul(us), adjective derivative of rīdiculum ridicule ( def. ) + -ōsus -ous ( def. )

Explanation

Did you just say that you could toss a rubber chicken over an ocean? Don’t be ridiculous, because ridiculous words are hard to believe, and they will make others laugh at you, not always in a good way either. The adjective ridiculous comes from the Latin word ridere, which means “to laugh,” but it’s also related to the word ridicule, which means to mock in a cruel way. A mocking and cruel laughter, that’s a common reaction to ridiculous situations. However, there are all different kinds of ridiculous, like seeing a fish holding an umbrella while riding a bike.
