it's like how king charles III is technically fully known as "Charles the Third, by the Grace of God of the United Kingdom of Great Britain and Northern Ireland and of his other Realms and Territories, King, Head of the Commonwealth, Defender of the Faith"
Welsh has so many consonants, I would not even have a clue where the syllable are. At least the Germans construct their monstrous words from slightly more understandable words. But then again, my German, despite only really being able to read it, is much better than my Welsh. If I actually took the time to learn the language, I would think much better of it.
