Matchboard → The word is formed from "match" (from Old French *macche*, meaning to fit or correspond) and "board" (from Old English *bord*, meaning a flat piece of wood). A matchboard refers to a board that fits or corresponds with another, typically used in construction or carpentry.
Think of a board that 'fits' or 'corresponds' with another — that's why a matchboard is designed to match up perfectly.
