'usage-based' originates from the combination of 'usage' and 'based', where 'usage' refers to the act of using something and 'based' indicates the foundation or basis.

'Usage' comes from the Old French word 'us', and 'based' is derived from the Old French 'basse', meaning 'foundation'.

Initially, 'usage-based' referred to systems or pricing models that were determined by the amount of use, and this meaning has remained consistent.
