Taking the forms of this and the identical Hundred name (v. supra ) the only etymology which can be suggested is that while the second element is beorg the first is the second element in the OE plant-name dweorge-dwostle , dweorge-d (w )osle , dwyrgedwysle , 'penny-royal.' This might possibly appear as ME dustel , One does not know just what plant the uncompounded form may have been used for in England, for it is not found in the OE vocabularies. Ekwall suggests alternatively that we may have an English cognate of OHG Dusilo , such as may lie behind Desning (Sf). If that is the case the OE name *Dysel (a ) must early have developed t between s and l . In any case one must explain the variation between l and n as due to Anglo- French influence (IPN 106).
