The Ơ Đu (O'du) are an aboriginal ethnic groupinVietnam and Laos. Their total population is more than 570.
The Ơ Đu are also commonly referred to as O'Du, O Du, Iduh, Tay Hat, Hat, and Haat.[2]
The Ơ Đu subsist mainly on slash-and-burn agriculture and raising cattle, augmented by hunting, gathering, and weaving.
The Ơ Đu have a language also called O'du, which is a Khmuic language.[2] The Khmuic languages are Austro-Asiatic.[2] There is some debate as to whether the Khmuic languages are of the Mon–Khmer branch, but the majority opinion is that they are not. Most Ơ Đu presently speak Thai.[citation needed]
