This study is about voice system in Burushaski, focusing especially on the middle voice (MV) construction. It claims that the [dd-] verbal prefix is an overt morphological middle marker for MV constructions, while the [n-] verbal prefix is a morphological marker for passive voice. The data primarily come from the Hunza dialect of Burushaski, but analogous phenomena can be observed in other dialects. This research is based on a corpus of 120 dd-prefix verbs. This research has showed that position {-2} on the verb template is occupied by voice-marker in Burushaski. The author argues that the middle marker is a semantic category of its own and that it is clearly distinguished from the reflexive marker in this language. The analysis of the phenomenon in this study only comes from the dialect of Hunza Burushaski, so a lot of research remains to be done on the other three dialects of Burushaski: Yasin dialect, Nagar dialect and Srinagar dialect.

This thesis was written to explore the structural case patterns of the Burushaski sentence and to examine the different participant coding systems which appear between noun marking and verb agreement. Verb suffixes follow nominative alignment patterns of agreement, while the verb prefix agrees with the affected argument as determined by semantic relations, as opposed to syntactic ones. The agent noun phrase is directly marked when highly active or volitional, suggesting a system of agent marking on the noun phrase and nominative alignment on the verb suffix. Nominative alignment also allows for a less marked presence of passive voice. Burushaski's agent marking is not entirely consistent; however, its nominative alignment is consistent. The conclusion is that Burushaski is not an ergative language at all.
