Abstract

This paper addresses the syntactic annotation of the verbs ER and BOL in copular constructions in Turkic-language treebanks in Universal Dependencies. ER is a defective verb, which has semantically empty content linking subjects to non-verbal predicates. BOL is a full verb with copula and semi-copula uses. The paper proposes a refined annotation strategy that treats ER consistently as an auxiliary copula and BOL variably as either an auxiliary copula or a lexical verb, depending on its semantic contribution in context. The aim of this proposal is to improve the consistency and cross-linguistic comparability of Turkic language annotations in UD.
