An Etymological Dictionary of the German Language/Karat

by Friedrich Kluge

Karat, n., ‘carat,’ not derived fro MidHG. gárât, f. and n., ‘carat,’ which in ModHG. must have been Gárat. The ModHG. has been more probably borrowed anew from Fr. carat or Ital. caráto; the MidHG. word has adopted the G. accent, while the ModHG. term preserves the accent of the Rom. word upon which it is based.
