That's not Welsh. It's the rot13 of the Welsh phrase in the comment replied to.
That's pretty much the point that I was making. When I see text that looks like a rot13 encoded string, it's usually Welsh. Other than one unlucky vowelless word, neither the original Welsh nor my reply look more plausibly real than the other.
Aeolun phrased it well!
Interesting fact: despite the common jibes about lack of vowels, Welsh has 7 vowels whilst English has 5! Like WiFi, just because you can't see it doesn't mean it doesn't exist.
I don't speak any Welsh. I've never even been to Wales. I still knew what that phrase meant and was able to identify you had rot13d it.
Failing to understand languages isn't as impressive as you think.
I'm sorry, I thought that we were involved in friendly discussion. I did not realize that this discourse is antagonistic for you. You are 100% correct and you win the argument that I did not realize you had.
