Our work deals with grammatical and syntactic features of the conjunction makar as found in texts from 15th – 17th c. (the Vlach-Bulgarian Charters and two Bulgarian damaskins, which are part of the Diachronic Corpus of Bulgarian Language; http://histdict.uni-sofi a.bg/textcorpus/list), which has further extended its use to become a widely used concessive conjunction in present-day Bulgarian. The talk will focus on the structure and semantics of the concessive conjunction in predicative and non-predicative concessive segments.
