Haplology and diplology of grammatical markers in Slavic and Baltic

Summary This article deals with Slavic and Baltic instantiations of grammatical haplology, i. e., situations where two constructions ‘share’ a grammatical marker. In addition to haplology of reflexive clitics, an analogous case of haplology of irrealis markers is examined. We further explore the potential of the notion of grammatical diplology, referring to situations where (as a result of oscillation in the choice of a host rather than of redundant marking) two instantiations of a grammatical affix are licensed by the same construction. Diplology must be kept apart from resolution of haplology, i. e. the occurrence of phonologically identical markers with different functions resulting from an original situation of haplology.
