Abstract:
Languages are an important part of our culturally diverse world, yet many of today’s languages are in danger of dying out. To save endangered languages, one must first understand the dynamics behind language shift: what are the driving factors of people giving up one language for another? Here, we model language dynamics in time and space starting from empirical data. We show that it is the interaction with speakers of the same language that fundamentally determines spread and retreat of a language. This means that a minimum-sized neighborhood of speakers interacting with each other is essential to preserve the language.
