Completely unreasonable, silly, or impossible to take seriously.
From Latin *absurdus* meaning “out of tune, discordant,” from *ab-* “away” and *surdus* “deaf, dull.” It originally suggested something that didn’t sound right.
Calling something ‘absurd’ is like saying it’s out of tune with reality, not just a little wrong. The word still carries that musical feeling: the situation is so off-key that your mind kind of winces.
