'absurd' originates from Latin, specifically the word 'absurdus', where 'ab-' meant 'from' and 'surdus' meant 'deaf' or 'dull'.

'absurdus' transformed into the Old French word 'absurde', and eventually became the modern English word 'absurd' through Middle English.

Initially, it meant 'dull or out of tune', but over time it evolved into its current meaning of 'ridiculous or unreasonable'.
