I think this page has a decent idea about starting with a language:
https://fluent-forever.com/the-metho...cabulary-list/ It's called "A Base Vocabulary List" but it also goes over different topics... Well, I looked at it to see how well I'm doing in Polish (which is the main language I'm studying these days), and I don't know a lot of those words.

(But a lot of slang having to do with various bodily excretions and procreation...)
Still gathering inspiration about Welsh. When I look at it in reality, it's just another language, with people going about their everyday business, pretty European in style. A little bit in decline, but at the same time with more speakers than Icelandic, which nobody seems to worry about...
What attracts me to it, what it is in my dreams, so to say, is a language of real-life elves, druids, Celtic legends, and castles, and landscapes... Which is for me a conflict, because I don't know if it's really Welsh. At least, modern Welsh. Maybe it's just the history of Welsh, a language that is in fact no longer written nor spoken, and which I'm actually not going to hear (which is important to me)...
