Person in Slavic relative clauses
Slavic languages present two strategies of agreement in relative constructions with locutor personal pronouns in the head. The verbal predicate of the relative clause can either agree in person with the head of the relative construction (distant agreement) or take third person marking, which is presumably associated with the relative pronoun. The distribution of these two strateges among the Slavic languages is not even, the first or second person agreement being predominant in East Slavic languages and in Czech, unlike the other Slavic languages. These data, complemented by a study of several other European languages, suggest that distant person agreement is preferred in pro-drop languages.
