Morphology

motion = move (transparent) = move + tion

Standard noun formation from the verb 'move' using the productive suffix '-tion', giving the sense 'the act or process of moving'.

Etymology

Motion comes from the Latin movere, which means 'to move', and it shares the same root as the English word move. So, motion means movement or the process of changing position.
