Belonging to the Oirat dialect of Mongolian, the Khoshut subdialect obviously shares many phonetic, grammatical, lexicological, and semantic features with other Oirat subdialects. However, the subdialect has some features and peculiarities in the system of personal pronouns. In terms of the category of person, the Khoshut subdialect has a system of personal pronouns comprising all the three persons: the first person (the speaker/s), the second person (the addressee/s), and the third person (the person/s spoken of). The pronouns for all the three persons have distinct singular and plural forms, and the pronouns for the first, second and third (proximal) persons have dual forms, which are formed with stems of the personal and demonstrative pronouns plus suffixes from the numeral expressing “two”. Due to the existence of the dual forms, the plural in the system of personal pronouns of the subdialect differs from that in other dialects or subdialects. Specifically, the plural in other dialects expresses “two or more” while that in Khoshut subdialect means “three or more”.
