An Etymological Dictionary of the German Language/Rankkorn

by Friedrich Kluge

Rankkorn, n., from the equiv. MidHG. rankorn, rankhorn, n., ‘quinsy (in pigs)’; allied to Du. wrong, which is used of the diseases of cows. Whether it belongs, by inference from the Du. word, to the pre-Teut. root wrank (see renken), is uncertain.
