Welcome to Geirfan, a dictionary for adult learners of Welsh. Geirfan was inspired by a collaborative corpus-based Welsh wordlist project led by researchers from Cardiff University, CorCenCC (the National Corpus of Contemporary Welsh), the National Centre for Learning Welsh, and CBAC/WJEC.

The dictionary is currently limited to 60 entries, because it is in its pilot-testing phase. During this phase, feedback from visitors about Geirfan's content and design is particularly valuable. This feedback will help to improve the dictionary and will shape the approach to creating future entries.

Whether you have criticisms, compliments, or questions, it would be great to hear from you! Reach Geirfan by email, or come and have a conversation on Mastodon or on Twitter.
