dimple: [13] Dimple originally meant ‘pothole’, and was not applied to an ‘indentation in the flesh’ until the 14th century. There is no surviving record of the word in Old English, but it probably existed, as *dympel; Old High German had the cognate tumphilo, ancestor of modern German tümpel ‘pool, puddle’. Both go back to a Germanic *dump-, which may be a nasalized version of *d(e)up-, source of English deep and dip.
