A Mexican documentary will continue to preserve aspects of the indigenous Zoque-Ayapaneco language, whose universe of ideas, beliefs and culture are on the point of vanishing when the last two native speakers, both in their 70s, pass away.

“We’re beginning to investigate and we’re discovering that it is the language that is vanishing most rapidly in Mexico and worldwide. It’s the one with the fewest speakers, just two, and they’re elderly. When they die, it will practically cease to exist,” said director Denisse Quintero, 28, in an interview with Efe.
