Re Cornish

I read somewhere, years ago, that the last Cornish speaker was a lady who died around 1810 and that she was visited on her deathbed by language scholars eager to speak with her and take notes on the language while they still could. Maybe the reports of the death of that language were premature, like Mark Twain's obit.

Anyway, it is sad, to me at least, that the rich variety of language is being impoverished. But, as pointed out by others, a language has to be spoken by a significant number of people to be a living, viable language. Efforts to preserve a language [Latin comes to mind] like a fly in amber are never very successful. And to my knowledge, there is only one dead language that has been successfully resuscitated, that being Hebrew.
