'cost-focused' originates from the combination of 'cost' and 'focus,' where 'cost' refers to the amount of money required for something, and 'focus' means to concentrate attention or effort.

'cost' and 'focus' have been used in English since the Middle Ages, with 'cost' deriving from the Latin 'constare' meaning 'to stand firm' and 'focus' from the Latin 'focus' meaning 'hearth' or 'fireplace.'

Initially, 'focus' meant 'hearth' or 'fireplace,' but over time it evolved to mean 'center of activity or interest.'
