An Etymological Dictionary of the German Language/Korb
Korb, m., ‘basket,’ from the equiv. MidHG. korp (b), OHG. chorp, korb (gen. korbes), m.; comp. Du. korf, m., ‘dosser.’ The usual derivation from Lat. corbis is opposed by phonetic considerations, and also by the fact that nouns equiv. in meaning but with differently graded forms also occur; according to ModHG. Brett and its gradation Bord (which see), MidHG. krëbe, m., ‘basket,’ and hence further ModHG. Krippe may also be connected with Korb (comp. too ModIc. karfa, f., and körf, f., ‘basket’?). It is not impossible that, in addition to an inherited OTeut. word, the Lat. term was borrowed at a later period; OHG. churib, plur. churbî, points perhaps to Lat. corbis (E. corb); further ModHG. Reff (1) seems to be an old cognate of Lat. corbis.
