Comprehensive study of V-V complex verbs in Avar

Avar使用由两个动词（V1和V2）组成的复杂动词。V1以非有限形式出现，例如名词修饰形式的现在时形式，完成式转换。本研究回答了以下问题：(1)V2位置使用了哪些动词，每个V2在哪些非有限形式下需要V1出现，每个V1-V2复合体有什么语义？(2)每个V2都用哪些动词作为V1，使用频率如何？(3)每个V1-V2复合体都有哪些语法属性（如大小写标记、及物性）？(4)有些v允许它们的v以两种非有限形式出现，以表达相同的意思。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?
