'non-profitable' originates from the prefix 'non-' meaning 'not' and the word 'profitable' from Latin 'profitabilis', where 'pro-' meant 'forward' and 'facere' meant 'to make'.

'profitable' changed from the Old French word 'profitable' and eventually became the modern English word 'profitable'.

Initially, it meant 'capable of yielding profit', but with the prefix 'non-', it evolved into its current meaning of 'not yielding profit'.
