| Vocabulary of any language is always in perpetual development. The development of vocabulary manifests itself in the creation of new words, dying out of old ones and evolution of lexical meaning. However, word-formation is an important way to create new words. Thus, it is of utmost importance to study the word formation of a language. This paper used the verbs in "Uyghur Tilining Izahliq Lughiti" as linguistic data, and selected out more than 476 verb roots, 2370 derivational verbs and 1676 compound verbs; Above mentioned verbs were analyzed by combining theories with data to study the construction system of verbs in modern Uyghur.In addition to the introduction, conclusion and appendix, this paper consists of altogether four parts. In introduction, the background and significance of the chosen topic, relative theories and research methods (the scope of morphology, the differences between inflectional and derivational change, morphological analysis, derivation, coversion, back-formation, compounding, the rules and restriction factors of word formation, lexicalization) and symbols and abbreviations used in the paper.First chapter is on the structure and classification of verbs in modern Uyghur. From the perspective of verb structure, the structure of verbs in modern Uyghur can be classified into two systems, which are word formation system and configuration system.
