Decorative or structural work consisting of a checkerboard pattern, as in masonry, embroidery, or inlay.
From 'checker' (checkered pattern) and 'work' (created object). Used since the Middle Ages to describe both the process and product of creating checked patterns in craftsmanship.
Medieval stone checkerwork—alternating light and dark stone in buildings—created striking visual effects and still stands after 800+ years because the pattern distributes weight evenly.
