Etymology: "Fingerbreadth" is a plain compound of "finger" and "breadth," meaning the width of a finger held against something to estimate a length. Its Middle English ancestors, "fynger brede" and "fyngerbrede," show the two parts were already joined as a unit in the Middle Ages, when people often judged measurements by body parts rather than by standard units. The older forms are a useful clue to how the word worked. "Brede" was the Middle English form of "breadth," and "finger" carried its ordinary sense, so the compound named a measure taken from the hand itself. That kind of measure was handy in trades and everyday work, where a craftsman could gauge a thickness or a gap by eye and hand without a ruler.
