Afterwards → It is formed from "after" (from Old English "æfter", meaning following in time or place) and "-wards" (a suffix meaning in the direction of). The word "afterwards" means in the direction of or at a time following something.
Think of 'after' as something that comes 'following' an event, and '-wards' indicating direction — so afterwards means at a time that comes after.
