Omani Arabic (also known as Omani Hadari Arabic) is a variety of Arabic dialect spoken in the Hajar Mountains of Oman and in a few neighboring coastal regions. It is the easternmost Arabic dialect. It was formerly spoken by colonists in Kenya and Tanzania, but most or all of them have shifted to Swahili. There are several distinct dialects of Omani Arabic, such as Dhofari Arabic and Shihhi Arabic.
