Comprehensive study of V-V complex verbs in Avar

Avar使用由两个动词（V1和V2）组成的复合动词。V1以非限定形式出现，例如名词修饰形式的现在时形式，完成体转换形式。本研究回答了以下问题：（1）V2位置使用的动词是什么，每个V2需要V1以何种非限定形式出现，每个V1-V2复合体有什么语义？(2)每个V2都有哪些动词用作V1，它们的使用频率如何？(3)每个V1-V2复合体有什么句法属性（例如格标记、及物性）？(4)一些V2允许它们的V1以两种非限定形式出现，以表达相同的含义。这两种形式的使用频率如何？

Avar uses complex verbs comprising two verbs (V1 and V2). The V1 appears in the non-finite form, e.g. the present tense form of the noun-modifying form, the perfective converb. This study answered the following questions: (1) What verbs are used in the V2 position, in which non-finite form does each V2 require the V1 to appear, and what semantics does each V1-V2 complex have? (2) What verbs are use as the V1 for each V2 and how often they are used? (3) What syntactic properties (e.g. case marking, transitivity) does each V1-V2 complex have? (4) Some V2s allow their V1s to occur in two non-finite forms to express the same meaning. How often the two forms are used?
