absurdus (Latin)
Where does "absurdus" come from?
The Latin adjective 'absurdus' is formed by combining the prefix 'ab-' with 'surdus'[1]. The prefix 'ab-' traces back through Proto-Italic from Proto-Indo-European '*h₂epó'[2], meaning off or away. The root 'surdus' has its origins in the Proto-Indo-European root '*swer-', which relates to ringing or whistling[3]. In Latin, 'absurdus' originally carried meanings of being discordant or harsh, as well as incongruous, illogical, silly, stupid, senseless, or worthless.
