The first chapter of this thesis gives an overview about the topic and a first introduction of chaining structures in Classical Tibetan. Chapter 2 deals with the general possibilities of clause combining and shows the necessity for a clear definition of the German term "Satz" (since it can refer both to 'sentence' or 'clause'), which is seen differently from the syntactical or logical point of view, respectively. An overview of grammar theories follows in chapter 3, leading to the continuum of clause combining from Lehmann (1988) who has described coordination and subordination as extreme poles on a continuum rather than as a dichotomy. The following chapter is focusing on linguistic terms usually used for the description of complex sentence structures, including coordination, attribute clauses, complement clauses, adverbial clauses, object clauses and serial verb constructions. Another concept to deal with are "chaining-structures" (Longacre 1985), a specific way of clause combining, occurring in languages which do not provide the choice between coordinate and subordinate structures. Classical Tibetan, a Tibeto-Burman language described in chapter 5, uses such chaining-structures. They are identified in chapter 6 in some texts of different style by investigating in detail on semantic and syntactic properties of complex structures. Other registers and mainly Modern Tibetan are used for comparison. It is the first work to apply the parameter of Lehmann (1988) for Classical Tibetan, showing not only the use of chaining structures, but also the existence of integrated clauses: complement clauses, attribute clauses and subject/object clauses are classified differently by being more integrated or even embedded in a larger structure. In addition, a comparison with Modern Tibetan shows a syntactic change, since it allows also syndetic coordination.
