Welcome to Geiriadur Prifysgol Cymru
GPC is the only standard historical dictionary of the Welsh language.
It is broadly comparable in method and scope to the Oxford English Dictionary.
It presents the vocabulary of the Welsh language from the earliest Old Welsh texts, through the abundant literature of the Medieval and Modern periods, to the huge expansion in
vocabulary resulting from the wider use of Welsh in all aspects of life in the last half century.
This vocabulary is defined in Welsh, and English equivalents are also given. Detailed attention is given to variant forms, collocations, and etymology.
The work is based on an ever-expanding collection of over two million citation slips gathered from a range of texts over many years.

GPC+ Help create a new resource
GPC+ is intended to offer access to some of the resources of Geiriadur Prifysgol Cymru (the University of Wales Dictionary of the Welsh Language) that are not available as part of the Dictionary itself – the slips bearing examples of words in their context collected over almost a century in preparation for editing the dictionary. But before the resource can be used, it must be created!
You will be able to contribute to this by transcribing slips. If enough people are willing to help in this way, over time there will be a very useful resource.
For further information click HERE.
Note: The transcription website is available in Welsh only as we believe that that some of the material would be too challenging for those who cannot read Welsh.
New words – The work continues.
A pivotal part of the ongoing editing of the Dictionary, of course, includes the adding of new words; work that goes on behind the scenes, as it were.
So, if you would like to get a feel of how GPC is developing and, to see a list of the words added since 2014, click here. We will update this list as new words appear.
Useful links: There are a number of useful Welsh dictionaries and term banks online. You can find a list of them here.
