'uncompensated' originates from the prefix 'un-' meaning 'not' and the word 'compensated,' which comes from Latin 'compensare,' meaning 'to weigh together.'

'compensare' transformed into the Old French word 'compensier,' and eventually became the modern English word 'compensate,' with 'un-' added to form 'uncompensated.'

Initially, it meant 'not balanced or offset,' but over time it evolved into its current meaning of 'not receiving payment.'
