Belabor is formed from "be-" (meaning thoroughly) and "labor" (from Latin "laborare", meaning to work). The word describes the act of working on something thoroughly or excessively, often to the point of unnecessary repetition or effort.
Think of 'working thoroughly' ('be-') on something ('labor') — that's why belabor means to work on something excessively.
