PPNoSyncCase: The number of case-marked forms of personal pronouns differs from that of nouns, but none are syncretic.
(based on Honti 1977: 275–276. and Csepregi 1998: 24–25.)
Nouns and demonstrative pronouns can have 9 cases (nom, loc, lat, apr, abl, transl, ins-fin, com-ins, abess). Apart from these 9 cases, the personal pronouns also have accusative and dative forms. Therefore, no syncretism with personal pronouns is possible.
