Hello, I'm new here so I hope I'm not posting something that's already been covered. Anyways, here it goes, how could Continental Celtic languages such as Celtiberian and Gaulish survive to modern day? Would they be better off surviving in the mountainous regions like the Alps and Pyrenees? I'm a bit of a linguiphile and take a great interest in dead languages. Once again I apologize if this has been covered already.
