girdle: English has two words girdle. The more familiar, ‘belt’ [OE], goes back, together with its relatives garth, gird [OE], and girth , to a prehistoric Germanic *gurd-, *gard-, *gerdwhich denoted ‘surrounding’. From *gurdcame the verb *gurthjan, which produced both gird and girdle (as well as relatives in other Germanic languages, such as German gürtel, Dutch gordel, and Swedish gördel, all meaning ‘belt’), while *gerd- formed the basis of *gerdō, acquired by English via Old Norse gjorth as girth. Girdle ‘metal baking plate’  (as in girdle cake) is a Scottish alteration of griddle (see GRID). => garth, gird, girth
