Research on lesser studied languages is vital for the advancement of theories of language acquisition. We discuss two areas where data from Eegimaa have the potential to produce innovative research: (1) language typology, with an overview of the complex demonstratives found in this language, and (2) learning environment and input speech. Here, we show that Eegimaa children learn to speak in a polyadic environment, where they receive input from multiple caregivers, siblings and other members of their community.
