Nguồn gốc từ

From Middle English rodde, from Old English *rodd or *rodde (attested in dative plural roddum (rod, pole)), of origin, but probably from Proto-Germanic *rudd- (stick, club), from Proto-Indo-European *rewdʰ- (to clear land). Compare rudda. For the root, compare rid. Presumably unrelated to.
