Need to know whether a Welsh form exists for an English place-name in Wales, or vice versa? Enwau Cymru is the website for you. It gives the details of the parish, traditional county and the unitary authority of the place in question, as well as providing a sound file with the correct pronunciation of some of the most prominent names found in Wales. It also identifies the location of the place-name on a map – very useful when you need to distinguish between the different Newports found in Wales when translating!
