/ɹɒd/

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