Mising is a Compound Word, it is believe that it may derived from “ami= man + asing=water” meaning ” Man who lived near the Banks of River”.
As per Historians there were no such word as Miri! There never a Tribe existed as Miri. It is believe that in ancient times the Priest of Adi people are called as “Miri” which derived from ” ami=man + iri=virtue” meaning ” Man who possesed Super Powers or worships Natural forces”.
In Assam most of the community people prefers to call themselves” Mising” only.
