Broader → It is formed from "broad" (from Old English "brād", meaning wide) and the comparative suffix "-er" (meaning more). The word "broader" means more wide or having a greater width than something else.
Think of something that is 'more wide' — 'broad' means wide, and '-er' indicates a comparison, so broader means it has greater width.
