Knighton /ˈnaɪtən/ (Welsh: Tref-y-clawdd Welsh pronunciation: [trɛvəˈklauð] or Trefyclo) is a small market town and community situated chiefly in Powys, Wales, within the historic county boundaries of Radnorshire. Lying on the River Teme, the town straddles the English-Welsh border; Knighton railway station, as well as a small part of the town's built-up area, is located in Shropshire, England. Knighton is the sixth largest town in Powys. The name Knighton derives from Old English meaning 'A settlement of servants' Cniht or cnihta (forming the now used 'knight' aspect) originally meaning servant rather than the oft mistaken 'Knight' as in the soldier. This was both an Anglo-Saxon settlement (though no trace of this has ever been located) and later a Norman fortified town. Tref-y-clawdd, its Welsh name, is not a translation: it means 'town on the dyke' (i.e. Offa's Dyke) and not Knighton, and is first recorded in 1262.
