Synchronically predicative possession constructions could be analyzed in two different ways: as locational possessive constructions or as genitive ones, e.g. moja dwa synka esi could be analyzed as 'I, two sons (exist)' or as 'my two sons exist'. However, possessive constructions with somewhat less frequent word order (e.g. tibe ju piat kapeka 'you have five kopeks') with the copula after the Possessor show that these constructions should be regarded as topic possession.
