Ross Perlin, author of Language City: The Fight to Preserve Endangered Mother Tongues in New York, examines the past, present, and future of the world’s most linguistically diverse city, New York. He will also discuss multilingualism, language policy, and the role technology plays in the evolution and documentation of languages. Today, half of the world’s 7,000-plus languages are growing increasingly endangered, while contemporary cities – supported by migration – are more linguistically diverse than ever before. As speakers migrate across the globe, linguists and language activists are racing against time to map and document lesser-known, minority, endangered, and Indigenous languages.
