'Niti' - real negative coordination inside a strict Negative Concord language?

There are two negative coordination constructions in Serbo-Croatian: ni...ni and niti...niti. The present paper focuses on the latter one, examining its syntactic distribution, as well as the place it occupies in the system of strict Negative Concord. A hypothesis that niti is an inherently negative coordination marker is explored, but closer scrutiny reveals it to be untenable. I show that niti...niti-coordination has to be analyzed as a semantically non-negative disjunction, as well as how it can fit into the system of Negative Concord.
