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.
