Can a language save your life?
Yes it can, even an ancient one from the 15th century.
Saved by Language tells the story of Moris Albahari, a Sephardic Jew from Sarajevo (born 1930), who spoke Ladino/Judeo-Spanish, his mother tongue, to survive the Holocaust.
Moris used Ladino to communicate with an Italian Colonel who helped him escape to a Partizan refuge after he ran away from the train taking Yugoslavian Jews to Nazi death camps. By speaking in Ladino to a Spanish-speaking US pilot in 1944 he was able to survive and lead the pilot, along with his American and British colleagues, to a safe Partizan airport.
We recommend viewing this 53 minute documentary with subtitles in Bosnian, English, Ladino (Judeo-Spanish), Portuguese or Spanish.
