The interpretation of this name clearly depends upon the relation of the name Mansfield to the name of the river Maun (supra 5) on which it stands and to the place called Mamesheued in the Perambulation of Sherwood Forest. That perambulation brings us from Hartrey Bridge (infra 125) by the great Nottingham road to the bridge at Mulneford and so up to Mammesheued and thence between the fields of Kirkby and Hardwick to Nuncargate. This means that Mamesheued must be the high ground to the north-west of Kirkby Hardwick (supra 121) where the Maun river rises. The most natural interpretation of the three names would seem therefore to be to take the river-name Mam or Mome as an original one, to interpret Mammesheued as 'source of the Maun' (v. heafod ) and Mansfield as 'open ground of the Maun,' i.e. open ground in the valley of the Maun, v. feld .This seems more natural than with Ekwall (DEPN) to take Mamesheued and Mansfield as referring alike to a hill called Mamm .
The phonological development would seem to have been from Mam (m )esfeld by a process of dissimilation to Manesfeld , Maunesfeld . From the new form of the town-name a new form Maun for the river-name developed and took the place of the earlier and more correct Mom or Mam . The ultimate history of the river-name is obscure. v.
