Dependency relations are needed for the development of a dependency treebank and a dependency parser.The guidelines 1 for the development of treebank for Sanskrit proposed a set of dependency relations.Use of these relations for the development of a sentence generator and a dependency parser for Sanskrit demanded a need for an enhancement as well as a revision of these relations.In this paper, we discuss the revised version of these relations and discuss the cases where there is a possibility of multiple tagging either due to the ellipsis of certain arguments or due to the possible derivational morphological analysis.This led us to arrive at specific instructions for handling such cases during the tagging.A treebank with around 4000 sentences has been developed following these guidelines.Finally we evaluate a grammar based dependency parser for Sanskrit on this treebank and report its performance.
