Illustration of "preposterous": "Preposterous" describes something that is so completely contrary to reason, common sense, or realit

What does "preposterous" mean?

"Preposterous" describes something that is so completely contrary to reason, common sense, or reality that it borders on the absurd. Think of the mental image of a person trying to carry an elephant in a backpack; the sheer impossibility and ridiculousness of the idea is exactly what makes it preposterous. In usage, this word carries a strong sense of indignation or disbelief. It is more formal and forceful than just saying something is "silly" or "wrong." It is frequently used in professional or intellectual arguments to dismiss an idea that the speaker considers fundamentally flawed or logically offensive.
