An Etymological Dictionary of the German Language/Möhre
Möhre, f. (not current in Suab. and Bav.), from the equiv. MidHG. mörhe, also more, morhe, f., OHG. moraha, morha, ‘carrot’; a non-mutated form occurs in ModHG. Mohrrübe; Goth. *maúrhô may be also assumned from AS. moru (for *morhu), f., and more, f., E. (dial.) more, ‘turnip.’ For a derivative of these cognates see under Morchel. From OTeut. morhô-n-, ‘carrot,’ Slov. mrkva and Russ. morkovĭ (prim. Slav. *mrŭky) seem to be derived.
