'engine-powered' originates from the combination of 'engine' and 'powered', where 'engine' comes from Latin 'ingenium', meaning 'skill or talent', and 'powered' is derived from 'power', which comes from Old French 'poeir', meaning 'to be able'.

'engine' evolved from the Latin word 'ingenium' through Old French 'engin', and 'powered' evolved from Old French 'poeir' to the modern English 'power'.

Initially, 'engine' referred to a mechanical device or skill, and 'powered' meant having the ability or capacity. Together, they now refer to being driven by a mechanical engine.
