'Parecen que lo olvidan': Plurals did it again

The distribution of DDPP in raising constructions –depending on the embedded clause’s formal properties– has been essential for Case Theory and movement. Likewise, the behavior of DDPP, according to agreement facts, has given rise to relevant discussions about the kind of movement involved (A-Movement/A’-Movement). Nevertheless, this distribution is not so clear in certain Spanish dialects, which shows a double agreement effects. It means that the embedded verb as well as the raising verb ( parecer ‘to seem’) present inflectional number (and person) morphology: Parece-n que lo olvida-n (seem.3PL that it forget.3PL ‘They seem to forget him’). The analysis of the data in these varieties allows us to define many characteristics which are relevant from a descriptive and a theoretical point of view. Descriptively, it is possible to identify some notable particularities, with respect to the position of the DP, which triggers agreement and the interaction of these constructions with dative experiencers as well ( Me parece que ... ‘It seems to me that...’). From a theoretical point of view, these data have consequences for approaches on agreement, on the relationship between Case and movement, and on the discussion regarding the Experiencer Paradox in Spanish. Additionally, they allow us to identify a new empirical domain in which a DP plural number feature has an active role in the Probe-Goal domain.
