甘青河湟方言导源于语言接触的语法型变同样波及差比句,使之呈现出相应的类型特征:名词性基准和动词性基准普遍存在分别适配的介词性标记和关联性标记;客体格、伴随格、从格助词和动词的连接式助词都可以用作基准标记并可以构成Y+M+A差比式。从格助词、连接助词差比标记和相应的Y+M+A差比式来源于对蒙古语言同类标记的借用和相应构式的复制;客体格、伴随格助词的差比标记功能则是在汉语比较动词与基准的句法语义关系的制约下获得的,相应的Y+M+A差比式来源于Y+M+V+A动词差比式,是本方言基于内外动因的语法创新。 Gan Qinghe dialect derived from the grammatical type of language contact change the same spread difference clauses, so that it presents the corresponding types of features: Nominal and verb basic benchmark prevalence fitted prepositional markers and related markers; object lattice , Accompanied by lattice, lattice adjutants and verbs connected adjuncts can be used as a reference mark and can form Y + M + A difference ratio. The parity of adjunct to adjunct, adjunct to adjunct and the corresponding ratio of Y + M + A derive from the borrowing of the Mongolian language mark of similar type and the copy of the corresponding constructs. The corresponding Y + M + A difference ratio is derived from the grammatical difference of Y + M + V + A, which is the grammatical innovation of this dialect based on internal and external motivation.
