The word kabui
is still a mystery to the kabui themselves. It is an alien word of which no
definite origin is known to the kabuis. The kabuis now days call themselves
Rongmei. It is a combination of two words RONG and MEI meaning SOUTH and PEOPLE
respectively. Thus Rongmei stands for the southerners,
the ancestral home of the kabuis lies in the mountain ranges in the Tamenglong sub division of Manipur and adjacent mountainous areas of Nagaland and Assam.
The Kabui settlement area within the territory of Manipur happens to be the southern portion of the vast tract of kabui country and hence those who settling in the southern part of their habitat within Manipur call themselves the Rongmei the southerners.(Life style, Indian tribes: locational practice, Volume 2: By Shiva Tosh Das)
