The paper deals with the spelling of cases of Polish proper names in Czech, the written nominative ending of which is preceded by the digraph ending in the so-called mono-functional letter i (conf. e.g. Świnoujś-ci-e, Bogaty-ni-a, Ka-si-a). It describes the essence of the problem, gathers all the relevant types of Polish proper names for consideration, enumerates cases in which Czech spelling could be (at least potentially) objectively problematic, presents possible arguments for possible Czech spellings and discusses them, and, finally, recommends one of them for general use.
