Morphology

action = act (semi-transparent) = act + ion

While 'act' is clear, the specific meaning related to machine operation is specialized.

Etymology

Action comes from the old Latin word agere, which means 'to do' or 'to drive', and you can see the same root in act and actor. So the action of a machine or firearm is the part that actually 'does' the moving or makes it work.
