'alkalinuria' originates from New Latin, combining 'alkali' from Arabic 'al-qaly' meaning 'ashes of the saltwort' and '-uria' from Greek 'ouron' meaning 'urine'.

'alkalinuria' was formed in the 19th century as medical terminology expanded to describe specific conditions related to urine composition.

Initially, it meant 'presence of alkaline substances in urine', and this meaning has remained consistent in modern medical usage.
