The word 'Koireng', believed to be termed by the Meiteis is, is a corrupt version of the word, Kolren or 'Koren'. Linguistically, Koireng is classified under the Tibeto-Burman of the Sino-Tibetanfamily of languages. Koirengs are generally short-statured, with straight black hair, dark brown eyes and brown skin. Koireng is a recognized scheduled tribe of India. They have linguistic and cultural affinities with some of their neighbouring kindred people such as the Aimol, the Tikhup, the Purum and the Kharam tribes of Manipur and the Ranglong, Hrangkhol of Tripura and the Biates.

Economy
The Koireng economy persists mainly on agriculture which they carry on by both wet method and shifting cultivation. Paddy, potato, ginger, yongcha, etc., are some of the main products. Gathering economy and basket products for commercial goods form trade and market. Hunting in the form of sports is persistent during off-seasons in the villages of Thanglong, Utonglok and Sadu.
The Koirengs' last major colonial stronghold, as they entered Manipur, was the Thangjing Hill range overlooking the pristine Loktak lake. Thangjing is derived from the Koren words, Thang = South, Ching=hill. Their historic dominance of this region was presumably a constant eyesore to the erstwhile kingdom of the Moirang clan. This proximity led to numerous aggressions. The Koirengs, already weakened after a major infernal disaster, were terribly defeated at the end. They ultimately underwent a diaspora in various parts of Manipur and North-East India. Today, the Koirengs are sparsely scattered around the surrounding foothills of the Imphal valley of Manipur, India. Tuiruong tiengmo chesik? Tuivai tiengmo chesik?
