Tolkien and Welsh provides an overview of J.R.R.Tolkien's use of Welsh in his Legendarium, ranging from the obvious (Gwynfa), to the apparent (Took), to the veiled (Gerontius), to the hidden (Goldberry).

Though it is a book by a linguist, it was written for the non-linguist with the goal of making the topic accessible. The unavoidable jargon is explained in a glossary, and the narrative presents an overview of how Welsh influenced Tolkien's story line, as well as his synthetic languages Quenya and Sindarin.
The study is based on specific examples of attested names, placed in the context of their linguistic and cultural background, while highlighting the peculiar features of Welsh, "the senior language of the men of Britain" (MC 189), that Tolkien found so intriguing. It supplements, rather than competes with Carl Phelpstead’s excellent Tolkien and Wales, which sidestepped the topic of the Celtic linguistics behind Tolkien's work.
