The Dani people live in the Baliem Valley of the Western Highlands.
Grand Valley Dani has established its own orthography during a conference between linguists of the Dutch New Guinea government and different missionary bodies in February 1961.
Verbs in Grand Valley Dani are highly inflected for many tenses.
Unless denoted in the table, verb forms are marked by personal markers.
This trait makes it an interesting field of research for language psychologists, such as Eleanor Rosch, investigating the Whorf hypothesis.
