Etymology: "Fingerwidth" is a plain English compound, formed by joining "finger" and "width" with no hyphen. "Finger" comes from Old English "finger," a word shared with Old Norse, Old Saxon and Old High German, and "width" is a noun formed from the adjective "wide," with the suffix "-th" (as in "length" or "depth") added to it in Middle English. Taken together, the word is a transparent measuring unit: it names the breadth of a finger held up to the eye or laid against a surface. Such compounds are rarely recorded as separate dictionary entries because their meaning is simply the sum of their parts. Its use is mostly informal, in measurements like "two fingerwidths of whisky" or "a fingerwidth of gap," where the unit is handy for estimating without a ruler.

Synonyms: fingerbreadth, digit width
