The Onge language (also spelled Öñge, Ongee, Eng, or Ung) is one of two known Ongan languages within the Andaman family. It is spoken by the Onge people in Little Andaman Island in India.
In the 18th century the Onge were distributed across Little Andaman Island and the nearby islands, with some territory and camps established on Rutland Island and the southern tip of South Andaman Island. Originally restive, they were pacified by M. V. Portman in the 1890s. By the end of the 19th century they sometimes visited the South and North Brother Islands to catch sea turtles; at the time, those islands seemed to be the boundary between their territory and the range of the Great Andamanese people further north. Today, the surviving members (less than 100) are confined to two reserve camps on Little Andaman, Dugong Creek in the northeast and South Bay.
The Onge were semi-nomadic and fully dependent on hunting and gathering for food.
The Onge are one of the aboriginal peoples (adivasi) of India. Together with the other Andamanese tribes and a few other isolated groups elsewhere in Oceania, they comprise the Negrito peoples, believed to be remnants of a very early migration out of Africa.
Onge used to be spoken throughout Little Andaman as well as in smaller islands to the north - and possibly in the southern tip of South Andaman island. Since the middle of the 19th century, with the arrival of the British in the Andamans, and, after Indian independence, the massive inflow of Indian settlers from the mainland, the number of Onge speakers has steadily declined, although a moderate increase has been observed in recent years. Currently, there are only 94 native speakers of Onge, confined to a single settlement in the northeast of Little Andaman island (see map below), making it an endangered language.
The Onge are one of the least fertile people in the world. About 40% of the married couples are sterile. Onge women rarely become pregnant before the age of 28. Infant and child mortality is in the range of 40%.
