The British language in its lustre, or A copious dictionary of Welsh and English : containing many more British words than are in Dr. Davies’s Antiquae linguae Britannicae dictionarium duplex ...

The first Welsh-English dictionary - Y Gymraeg yn ei Disgleirdeb or The British language in its lustre was the first Welsh-English dictionary to appear in published form. This volume, by the almanacer Thomas Jones, was pocket sized and relatively cheap. Jones used John Davies’s Welsh-Latin section in Dictionarium Duplex as a starting point for his publication. However, this dictionary was not intended for the educated minority, like Davies’s Latin version, but rather the ordinary population. Jones wished to enhance the lower class’s ability to write and spell both in Welsh and English through Y Gymraeg yn ei Disgleirdeb.
