Orsu
Orsu is an LGA (Local Government Area) and tribe in the Imo State of Nigeria. Orsu is also the name of the dialect of this people. They are an Igbo sub-group located west of Orlu town to south of Ozubulu, north of Oguta and in the general areas around Oru, Orsu, Orlu, Njaba, Ihiala, Nnewi south and Oguta LGAs.
Over the years, the identity of the Orsu and their unique dialect of Igbo is fading away and a more centralized form of Igbo is popular among Orsu speakers.
