'expense-oriented' originates from the English word 'expense' combined with the suffix '-oriented', where 'expense' meant 'cost or charge' and '-oriented' meant 'focused on or directed towards'.

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

Initially, 'expense' meant 'outlay or expenditure', but over time it evolved into its current meaning of 'cost or charge'.
