Except with us, the major problem is to get anyone to speak the other Celtic languages, and even with us, people nowadays can all speak English as well, so only real patriots want to put in the heavy labour of bi-lingual conversation. When I was a kid, masses of my relations were monoglot Cymry Cymraeg, but nowadays we rely on cousins from Patagonia for a purer version of the language, in the sense that it is influenced by Spanish, not English. For a linguistic exercise, never mind Gabriel, Garcia, Marquez - try speaking Cymraeg learned as a boy to a cousin who speaks only Spanish by way of someone who speaks Spanish and the 'Welsh' of Patagonia, which is odd - people on the Cardiff bus were practically falling out of their seats. The Bretons and Cornish are not that distant - Cornish/Cernoweg is almost a dialect of Cymraeg, and the problem with Breton is the spelling. My parents didn't teach me Cymraeg, believing the Country was finished, but fortunately they spoke it together when they didn't want me to know what they were talking about, so I learned fast. They wouldn't let Galicia into the Celtic League because the language is gone and they were anxious to avoid racism.
As to non-European languages, I'm sure the general principle is sound, but Chinese and English are alike in having a very simplified grammar, so I found that easier than Latin or Greek, with which I still struggle rather unavailingly! So it goes!
