摘要：The present article examined the function of one of Greenberg's implicational universals in the Laki language from a typological point of view and studied the word order in sentences with adposition in this language. In data analysis, the unique function of the verb “ha” became the main focus of the research. The analyses illustrated that, unlike other verbs of this language, in the sentences with adposition, in some grammatical features, this verb has the character of verb-final. In order to study this phenomenon, the article first identified and determined different linguistic elements that are the source of this unique function in different contexts. Then, referring to some important explanations of language typology, it explained the cause of this linguistic phenomenon and indicated that some motivation or forces are involved in explaining the different behavior of the verb “ha”.
