Eyak is an extinct language that was spoken in Alaska, near the mouth of the Copper River. Marie Smith Jones, the language’s last native speaker, as well as the last full-blooded Eyak, died in 2008 at the age of 89. Before her death, she worked with experts to compile a dictionary that would allow future generations to revive the language. With no native speakers left in the world, Eyak became a symbol in the effort against language extinction. Which languages are the closest relatives to Eyak? Discuss
