Border can refer to either the line (a fence along the border of the property) or the adjacent area (a frame with a wide border). Edge refers to the bounding line formed by the continuous convergence of two surfaces (sat on the edge of the wall) or to an outer line or limit (a leaf with serrated edges; stopped at the edge of the water). Margin generally refers to a strip that runs along an edge or border: the margin of the page; the grassy margins of a path. A verge is an extreme terminating line or edge: the sun's afterglow on the verge of the horizon. Figuratively it indicates a point at which something is likely to begin or to happen: an explorer on the verge of a great discovery. Brink denotes the edge of a steep place: stood on the brink of the cliff. In an extended sense it indicates the likelihood or imminence of a sudden change: on the brink of falling in love. Rim most often denotes the edge of something circular or curved: a cup with a chipped rim; the rim of a basketball goal; lava issuing from the rim of the crater.
