'nonurinating' originates from English, formed by combining the prefix 'non-' (meaning 'not') with the present participle 'urinating' from the verb 'urinate' (to pass urine).

'urinate' derives from Latin 'urinare' (to pass urine) and entered English via Late Latin/Modern scientific usage; 'non-' is a productive English prefix used to negate adjectives or participles, producing 'nonurinating' by straightforward composition.

Initially the elements meant 'not' + 'to pass urine'; over time the composed form has been used in specialized/clinical contexts to mean 'not producing or passing urine.'
