'anuric' originates from New Latin/medical coinage, ultimately from Greek elements: the prefix 'a-' meaning 'without' and 'ouron' meaning 'urine'.

'anuric' was formed in modern medical English from New Latin 'anuria' (from Greek 'a-' + 'ouron'), with the adjectival suffix '-ic' added to indicate relation to the condition 'anuria'.

Initially it literally meant 'without urine' and over time has remained a clinical adjective meaning 'characterized by absence of urine (anuria)'.
