'aneuric' originates from the medical term 'anuria', which comes from Greek, specifically the prefix 'an-' meaning 'without' and 'ouron' meaning 'urine'.

'anuria' was adopted into medical Latin and then English, and the adjective form 'aneuric' was created to describe the condition of having anuria.

Initially, it meant 'without urine', and it still refers to the state of not producing urine in modern medical usage.
