Somerset (pronunciation (help·info); IPA [ˈsʌmɚˌsɛt]) is a county in South West Englan. The county town is Taunton, which is in the south of the county. The ceremonial county of Somerset borders the counties of Bristol and Gloucestershire to the north, Wiltshire to the east, Dorset to the south-east, and Devon to the south-west. It is partly bounded to the north and west by the coast of the Bristol Channel and the estuary of the River Severn. The traditional northern border of the county is the River Avon, but the administrative boundary has crept southwards, with the creation and expansion of the City of Bristol, and latterly the county of Avon and its successor Unitary Authorities in the north.
