This paper offers a comprehensive LFG-account of three Hungarian constructions that can host what at first seem to be instances of the selfsame demonstrative pronoun: adnominal demonstratives, demonstrative correlates of finite that-clauses, and demonstrative correlates of noun phrases in topic left dislocation. We treat synchronic variation in this domain as a result of different historical paths of grammaticalization, and provide an outlook on the pertinent diachrony.
