Aftermost → It is formed from "after" (from Old English "æfter", meaning following in time or place) and "most" (from Old English "mōst", meaning greatest or most). The word "aftermost" means the furthest back in time or position, or the last in a sequence.
Think of something that is 'following' ('after') and is the 'greatest' or 'most' in that position — that's why aftermost means the last or furthest back.
