Welsh place name search

"You don't have to be a language expert to work out what some of the place names in Wales may mean. This new search tool aims to help uncover the meaning behind them.

It includes hundreds of Welsh, English, Norse and French word elements which make up the names of our cities, towns, villages and even houses, farms, streets and buildings."
