Morphology

action = act (transparent) = act + ion

The noun denotes the result or process of acting (e.g., the movement or effect produced), which is directly derived from 'act' + '-ion'.

Etymology

Action comes from old Latin agere 'to do', and it helps to think of it as the 'doing' power of nature; the action of wind or water is the work those forces 'do' to shape the land.
