Tailender → It is formed from "tail" (from Old French *tail*, meaning the rear or end part) and "-ender" (a suffix indicating a person or thing that is associated with or characterized by). The word "tailender" refers to a person or thing that is at the end or rear of a group or line.
Think of someone at the 'end' ('tail') of a line — that's what a tailender is, a person who is last.
