On typological investigations of Serbian and other Slavic languages by Academician Predrag Piper

In this brief review of the broad field of research of Academician Predrag Piper, we tried to point out some typologically relevant similarities and differences between Slavic languages, especially regarding pronouns and numbers (which were much less discussed in the Slavic scientific community), as well as morphological-syntactic categories of impersonality and personality. Predrag Piper?s work on describing morphological and syntactic categories in Slavic languages concerning their semantic and functional content, based on the theory of semantic localizations, offered numerous answers and provided authoritative and plausible insight and explanations for a large number of issues that had rarely been investigated. Predrag Piper left numerous solutions and ideas in the field of semantic categories, in which new directions have opened for typological examinations of categorial meanings within modern linguistic theories.
