What is "salwarpe"

Salwarpe is a small village in the Wychavon district of Worcestershire, England, less than two miles south west of Droitwich, but in open country. The name is also spelled Salwarp, and in the time of John Leland was recorded as Salop. No longer a civil parish in its own right, Salwarpe now shares a parish council with Hindlip and Martin Hussingtree.
