fettle (n.)
"condition, state, trim," c.1750, Lancashire dialect, from fettle (v.) "to make ready, arrange" (14c.), perhaps from Old English fetel "a girdle, belt," from Proto-Germanic *fatilaz (cognates: German fessel "fetter, chain," Old Norse fetill "strap, brace"), from PIE *ped- (2) "container" (see vat).
