The responsibility for advising on the standard forms of Welsh place-names lies with the Welsh Language Commissioner. Temporarily, whilst the Welsh Language Commissioner’s new website is being developed, the Welsh Government is hosting the List of Standardised Welsh Place-names on the BydTermCymru site.
You can search for a whole name or a part of a name by browsing the list in alphabetical order, or by using your computer’s usual search functions. Filtering by local authority may make it easier to find the standard form of a particular name.
You can download the list under an open licence agreement. Further information about the licence and the copyright may be found at the bottom of this page.
The Commissioner’s Place-names Standardisation Panel uses these National Standardisation Guidelines to help it form its recommendations:
If you have not managed to find the name you or searching for, or if you have a question about standardising place-names or any related matters, please send a message to: email@example.com.
Note that the Welsh Government Translation Service is not responsible for this resource.
