Yeah, probably that’s the main reason! I remember reading a reply from a person who lived in Ireland but wasn’t Irish, and that person was really skeptical about learning Irish, and insisted that a language should be no more than a means of communication and therefore we all need to learn the languages that are widely used (English).
I’ve finally found time to start learning seriously and I can see what you mean by saying Skeul an Yeth isn’t the most exciting of textbooks! It’s really quite dry, but I suppose one can always dilute it with some short fun texts or videos (provided that one finds them). Do you perchance know any blogs in Cornish?
