Kho'ini (alternatives: Xoini, Xo'ini, Khoeini, or Di) is a Tatic dialect or language spoken in northwestern Iran, and is one of many Western Iranian languages. It is spoken in the village of Xoin and surrounding areas, about 60 kilometres (37 mi) southwest of Zanjan city in northern Iran. The Xoini verbal system follows the general pattern found in other Tati dialects. However, the dialect has its own special characteristics such as continuous present which is formed by the past stem, a preverb shift, and the use of connective sounds. The dialect is in danger of extinction.
