The term 'movement-dependent' combines 'movement,' from the Old French 'movoir,' meaning 'to move,' and 'dependent,' from the Latin 'dependere,' meaning 'to hang down from.'

'Movement' evolved from the Old French 'movoir' to the modern English 'movement,' while 'dependent' evolved from the Latin 'dependere' to the modern English 'dependent.'

Initially, 'movement' referred to the act of moving, and 'dependent' meant relying on something else. Together, they describe something that relies on movement.
