Etymology

The word "panel" traces back to the Latin pannus (cloth), reflecting its early use to describe a piece of fabric or material. Over time, it evolved in Old French to denote a flat, rectangular segment (e.g., of a door or wall). The suffix -el subtly reinforces the idea of a smaller, defined unit. By the 14th century, "panel" expanded metaphorically to describe groups (e.g., jury panels), likening them to assembled "pieces" of a whole.
