Dimitrova, Margarita2026-07-102026-07-1020263033-0599 (Online)https://doi.uni-plovdiv.bg/handle/store/1034The present paper addresses negation in yes-no questions focusing on data from Bulgarian. Considering that Bulgarian yes-no questions are structures licensed by the interrogative particle li (Rudin 1986, Rudin et al. 1999, Izvorski 1995, Dimitrova 2020, among others), we more particularly concentrate on the relation between li, the negation marker and the licensing of Negative Concord. Based on the intriguing contrast concerning the blocking of Negative Concord and the behaviour of n-words, we will argue against the previous accounts claiming that negation in yesno questions is expletive, i.e. void of negative content. Rather, we suggest that the blocking of Negative Concord results from the occurrence of the interrogative particle li. In view of the Bulgarian data and building on previous analyses, namely Dimitrova (2020), we suggest that what prevents the licensing of n-words and moreover contributes to the characteristic positive bias these structures denote is verb movement to functional projections of the Left Periphery accounting for the speaker’s evaluations and kind of attitude (Ambar 2000, 2003, Yoon 2011, Giannakidou 2016).otherOther
