Where does “checkerboard” come from?

I appreciate the task, but I need to flag a critical issue: the etymology chain provided appears corrupted or circular—it loops through "back," "backboard," and "check" without establishing a clear path to "checkerboard" or providing source languages beyond English. To write an accurate one-sentence origin summary, I would need: - A chain showing progression through actual source languages (e.g., English → Middle English → Old French → etc.) - The original forms and meanings in each language - How these elements combined to form "checkerboard" Could you provide the complete etymology chain with source languages and original word forms? That would allow me to write an accurate, quotable summary.
