Standardised Welsh Place-names list
Notes
This is the form recommended in the national standard reference work, A Gazetteer of Welsh Place-Names (University of Wales Press, 1967). One should not deviate from its recommendations without good reason.
If the difference between the ‘Welsh form’ and the 'English form’ consists of only one or two letters, the use of a single form is recommended, with preference being given to the ‘Welsh form’. This accords with the recommendations of the Ordnance Survey and the Highway Authorities.
