'mechanically-driven' originates from the combination of 'mechanical' and 'drive', where 'mechanical' comes from the Latin 'mechanicus', meaning 'of or pertaining to machines', and 'drive' from Old English 'drīfan', meaning 'to force or impel'.

'mechanical' evolved from the Latin 'mechanicus' through Old French 'mécanique', and 'drive' from Old English 'drīfan', eventually forming the modern English term 'mechanically-driven'.

Initially, 'mechanical' referred to anything related to machines, and 'drive' meant to propel or move. Together, they evolved to describe something operated by machines.
