An Etymological Dictionary of the German Language/Annotated/Rind
Rind, neuter, ‘horned cattle,’ from the equivalent Middle High German rint (genitive rindes), Old High German rind, earlier hrind, neuter; Gothic *hrinþis, neuter, is wanting; Anglo-Saxon hrŷþer (hrîðer, hrîð-), Middle English rother, Dutch rund, ‘horned cattle,’ imply Gothic *hrunþis, a graded variant allied to Rind, Gothic *hrinþis. Old High German hrind is usually connected, like Hirsch, with the stem ker, ‘horn, horned’ (see Horn), appearing in Greek κέρας, and also with Greek κριός, ‘ram.’ The German word is, however, probably not allied to these words.
