The Lingo Newydd people have just announced this news website for leaners: https://lingo.360.cymru/ and there’s this article in Nation.Cymru about it and explaining the thinking behind it: https://nation.cymru/news/new-news-website-for-welsh-language-learners-launched-at-urdd-eisteddfod/
Currently, as you might expect, 7 out of the 10 articles focus on this week’s Urdd Eisteddfod, but the site appears to be aimed at learner’s of all ages.
