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 the Welsh form 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 Cocyd’ (in Cockett). It can also be contracted following a vowel in accordance with the rules of Welsh grammar, e.g. ‘mynd i’r Cocyd’ (going to Cockett).
