I just came across this lovely Facebook page called Brythonic Languages Word of The Day (WOTD). In short, it gives you an English world of the day, as written in Brezhoneg, Kernewek, and Cymraeg. (Breton, Cornish, and Welsh).
This may be of keen interest to anyone learning any one of the Brythonic languages, and/or to those who love etymology and learning cognates in other languages, or Brythonic/Celtic languages in general.
I've happily liked the page, and although I'm not actively learning a Brythonic language, I love learning words of Brythonic origin.
