Abstract
Complex verb forms in Turkish language are compound verb forms consisting of an auxiliary or full verb with a noun complement. The primary objective of this paper is to analyze morphological, functional and semantic aspects of complex verb forms used in Atabetü’l-Hakayık which was written in Karakhanid Turkish. Considering the fact that Karakhanid Turkish is a link between Old Turkish and Middle Turkish, an analysis like this should emphasize the fact that complex verb forms were used in Old Turkish and Middle Turkish periods of the development of Turkish language. Also, the analysis should show which complex verb forms are still in use in Modern Turkish language. In fact, it should answer the question whether certain complex verb forms have kept the same function and meaning in Modern Turkish language.
