absurd

Synonym discussion
Sense: adjective/1
All five words mark something as not deserving serious thought, but they differ in tone and force. 'Silly' is the mildest and often affectionate — a child wearing socks on their hands is silly, not absurd. 'Absurd' is cooler and more analytical: the speaker stands back and judges the idea as outside reason. 'Ridiculous' is closer to absurd but more emotional, often spoken in irritation: 'This price is ridiculous!' 'Ludicrous' is stronger and more formal, suggesting the listener should laugh out loud. 'Preposterous' is the most formal and indignant — usually reserved for claims the speaker finds offensive, as in 'a preposterous accusation'. So you might call a friend's plan silly, the price of a cupcake ridiculous or absurd, a movie scene ludicrous, and a politician's denial preposterous.

Etymology
English borrowed 'absurd' in the mid-1500s from Middle French 'absurde', which came from Latin 'absurdus' meaning 'out of tune, harsh, foolish'. The Latin word is built from 'ab-' (away from) and 'surdus' (deaf, dull-sounding) — so the original picture is of a sound that hurts the ear, then by extension a thought that hurts the mind. The philosophical noun sense, 'the absurd', is much younger, growing out of twentieth-century French existentialist writing, especially Albert Camus.
