Etymology: "Fingerwidths" is simply the plural of "fingerwidth," a noun meaning the breadth of a finger, used as a unit of measurement. The base word is formed from "finger" and "width," both native English words with Old English roots: "finger" traces to Old English "finger," and "width" is built from "wide" with the suffix "-th," the same pattern found in "length" and "depth." The plural follows the ordinary English rule of adding "-s" to a noun, so "fingerwidths" refers to several such measures, as when a recipe or a carpenter's instruction calls for a depth of two or three fingerwidths.
