And a final honourable mention for Evangeline Walton’s Mabinogion Tetralogy. Not a translation, but a creative reimagining, it still stays faithful to the source material. It's a far more accessible gift for someone who might want to experience the stories, rather than grapple with the text!
5/5

My own go-to is often Patrick K. Ford’s translation. The prose isn’t as vivid as Davies’s and it doesn’t cover the entire collection, but the sheer weight of footnotes and analysis more than makes up for that. An ideal gift for someone interested in studying, rather than just reading, the text.
4/5

Next is Sioned Davies’s translation, the safest gift for anyone curious about the text but not quite ready for a scholarly deep dive. It strikes an excellent balance between clarity and literary rigour, and it’s the one people will most often point you toward.
3/5

We begin with Lady Charlotte Guest’s original translation. Brief, I wouldn’t recommend it for actual reading. But the artwork in the Alan Lee illustrated edition is glorious. Perfect for someone who just wants to occasionally take it off the shelf and flip through the illustrations!
2/5

(Likewise, I'm not a native speaker, so take that as you will...! There are also often slight regional differences).

The 'iw' would be pronounced like 'you'. It'd be a bit like 'pews' in English, but with a soft 's' like at the end of 'moose'. Something like p-YOU-s.

Not quite, the 'u' at the start would be pronounced like it's an 'i'... :)

And while you're there, don't forget to Wishlist 'Tales from the Mabinogion', if you haven't already!

Oh, I don't know that one, but the shipwreck there would make a lovely reference!
But no, the three that I've used the most as references are Skrinkle Haven, Caerfai Bay, and Tresaeth (adding in a waterfall at the end of the beach is on my to-do list!).

A deodorant stick, iirc!
