The paper proposes a novel data representation inspired by Universal Dependencies (UD) syntactic trees, which are extended to capture the internal morphological structure of word forms. As a result, morphological segmentation is incorporated within the UD representation of syntactic dependencies. To derive the proposed data structure we leverage existing annotation of UD treebanks as well as available resources for segmentation, and we select 10 languages to work with in the presented case study. Additionally, statistical analysis reveals a robust correlation between morphs and sets of morphological features of words. We thus align the morphs to the observed feature inventories capturing the morphological meaning of morphs. Through the beneficial exploitation of cross-lingual correspondence of morphs, the proposed syntactic representation based on morphological segmentation proves to enhance the comparability of sentence structures across languages.

We conduct a morphosyntactic investigation into the light verb constructions (LVCs) or the verbo-nominal predicates in South Asian languages. This work spans the Indo-Aryan and Dravidian language families in treebanks based on Universal Dependencies (UD). For the selected languages we show how well the existing annotation guidelines fare for the LVCs. We also reiterate the importance of the core and oblique distinction in UD and how informative it is for making accurate morphosyntactic annotation judgments for such predicates.
