What is "pinvin"

Pinvin is a village in Worcestershire, England, a little to the north of Pershore, about south-east of Worcester, and about north-west of Evesham and is the location of Pershore railway station. The name is thought to come from 'Penda's fen' after the Mercian King Penda. David Rudkin's TV play Penda's Fen (1974) was set here. In that award-winning film, which was originally commissioned and screened as part of the Play for Today series, there is a strong reference to the origins of the place name in a scene where a local workman is painting a road closure sign. He paints "PINFIN" and is verbally corrected by the boy who is the chief character. The suggestion is that the road sign painter knows the origin of the name and may be one of the local followers of the Old Religion. The boy subsequently discovers that that the name was formerly Pinfin, and Penda's Fen from a book in his father's library.
