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.
Definite article
The Welsh definite article (y/yr) should be included in full and capitalised when preceding this name on signage where the place-name is the main focus of the sign. Further advice on how to display place-names on signage can be found in the technical guidance on our website.
When writing this name as part of a Welsh sentence, the definite article should be shown in lower case (e.g. ‘yn y Glais’ (in Glais). It can also be contracted following a vowel in accordance with the rules of Welsh grammar, e.g. ‘mynd i’r Glais’ (going to Glais).
Although it is expected that a single form including the definite article be displayed on signage, there is no need to precede the name with the definite article within an English sentence, e.g. ‘going to Glais’.
