I’ve been working on this mini series of episodes about minority languages and the threats they face and how they survive. Last episode, Welsh speakers took the drastic step of migrating to Argentina. But in researching it all, I keep referring back to a pair of Allusionists from a while ago: The Key. Part one, Rosetta, was about how a language survives in a physical form when its humans die, featuring the smash hit archaeological object the Rosetta Stone, and its namesake the Rosetta Disk, the linguistic key to the future. Part two is about how to decipher a dead language and why it might have died.
