'unmonetize' originates from the prefix 'un-' meaning 'not' or 'reverse' and the word 'monetize', which comes from Latin 'monetizare', meaning 'to coin money'.

'monetize' transformed from the Latin word 'monetizare' and eventually became the modern English word 'monetize'. Adding the prefix 'un-' created 'unmonetize'.

Initially, 'monetize' meant 'to coin money', but over time it evolved into its current meaning of 'to convert into a source of income'. 'Unmonetize' reverses this process.
