Sinaugoro

Sinaugoro is an Oceanic language of the Central Papuan Tip group, one of the Sinagoro–Keapara languages alongside Hula and Keapara, and a close relative of Motu, the speech of the Port Moresby coast. It is spoken in the coastal villages of the Rigo District, immediately east of the Motu homeland.

The two peoples shared the trading world of the hiri, voyages in which seagoing canoes carried Motu clay pots west to the Gulf of Papua and brought back sago. Over the centuries such contacts turned a simplified form of Motu into the region's trade tongue.

In 1606 the Spanish expedition of Luis Vaez de Torres sailed along this southern coast of New Guinea, the first Europeans known to have done so.
