Iresim
Iresim, also spelled Yerisiam, is an Austronesian language of the shoreline of Cenderawasih Bay in Nabire Regency, Central Papua. It forms a small subgroup with its closest relative Yaur, and with Umar more distantly, within the Cenderawasih Bay branch that descends from the ancient seaborne Austronesian settlement of New Guinea's northern coast.
