Isaac Yousefzadeh is in mourning for his mother, who passed away a few weeks ago. But with her death comes a second, more subtle loss—that of her language, Judeo-Kashani, which is now on the verge of extinction. “It’s like somebody is sick in bed and in another few days or years he will die,” he said. “That’s it.”

The language’s speakers trace their roots to Kashan, a city in central Iran where Judeo-Kashani had been spoken for centuries. But in the past several decades, the Jews of Kashan have scattered—first to Tehran, and later around the world—and their descendants have adopted different languages. Virtually the only speakers left are a handful of Jews from Yousefzadeh’s generation who were born in Kashan, a city that no longer has any Jewish residents. They are the end of the linguistic line. “It’s a language that each day, the number of people that know it is less and less,” said Yousefzadeh. “In 20 years, I’d say no one would speak it. Because they’re dying each day.”
