In this article, we investigated a dialect of Ewenki Language, which is spoken in Samajie(薩馬街) near Jalantun(札蘭屯), Hulunbuir-meng, Inner Mongolia, China. The dialect is somewhat different from Hailar dialect of Ewenki (that is Solon) in that the formal is free from Mongolian influence and preserves old forms. The informant`s name is Haher[xa:x◎r] of 72 years old.

For example p[p^h], b[b_.]. [2] Grammatical Structures In conjugation part, various case makers are developed. 10 case makers were found to which possessive personal suffixes follow optionally. In this dialect there weren`t complexly developed directive markers which are reported to exist in Hailar dialect of Ewenki(i.e. Solon). Directional, elative, goal were marked by ablative. There also was no indefinite accusative which is different from accusative in Solon. In this dialect inflectional and derivational suffix is fully developed. In indicative, voluntative and imperative mood personal ending optionally follows to preceding tense suffix. Verbal noun which constructs nominal and adnominal clause shows opposition between imperfect and perfect. As another Altaic languages, there present various converb forms. Some derivational suffixes represent grammatical category of causative, passive, aspect, and modality. Auxiliary verb constructions which is constructed from auxiliary verb preceded by converb ending, represent grammatical function, mainly aspect and modality. To present negation, three different way is used in case it is nominal predicate, verbal predicate and imperative respectively.
