Differential object marking in Modern Hebrew: from definiteness to partitivity

This paper investigates the change in differential object marking (DOM) currently exhibited in Modern Hebrew. To date, the consensus in the theoretical literature on Hebrew has been that the object marker 'et' is only licensed in the context of definite DPs. We observe, however, that in Modern Hebrew partitive indefinite DPs may also be preceded by 'et'. Here, we experimentally investigate this change in the distribution of 'et'. Using a judgment task, we asked 41 native Hebrew-speaking adults to rate sentences with 'et'-marked indefinite object DPs on a 5-point acceptability scale. Our results reveal that partitive items received a considerably high acceptance score, with an overall average of 3.6/5. In addition, we found a main effect for object-position and quantifier-type. In particular, acceptability of 'et'-marked partitives increased significantly for topicalized DPs and for DPs that contained proportional quantifiers (as opposed to cardinals). These data support the analysis of 'et' as a DOM marker. We propose that Modern Hebrew is currently undergoing a process of change, whereby the distribution of its object marker is shifting in the direction of the Turkish DOM pattern, along the Definiteness Scale proposed by Aissen (2003). Further, the Hebrew facts provide novel evidence for the relevance of this scale not only in a synchronic, but also in a diachronic investigation of DOM. Moreover, they point to a special status of partitivity among specific DPs, suggesting that it should be distinguished as a separate category on the Definiteness Scale.
