Enrol → It is formed from "en-" (meaning to cause to be in) and "roll" (from Old French *rolle*, meaning a list or document). The word "enrol" means to cause someone to be included in a list or register.
Think of 'causing to be in' ('en-') a 'list' ('roll') — that's why enrol means to register someone.
