This article investigates the placement of subjects and objects in American heritage Norwegian (AmNo). While previous studies of argument placement in AmNo (Anderssen & Westergaard 2020) have only included present-day heritage and homeland speakers, we make use of new corpus resources and compare present-day heritage speakers to an older generation of heritage speakers, emigrant speakers, and homeland dialect speakers born around the time of mass emigration. The study includes three positions in the clause: the initial position (Spec-CP) in main clauses, and placement before and after negation (i.e., subject shift and object shift). The results show that while the structure of the C-domain appears to be intact, there is an increasing preference for SV order in the heritage language (see also Westergaard & Lohndal 2019, Westergaard et al. 2021). We argue that this has consequences for the distribution of subjects and objects further down in the clause; however, apart from this, the principles for subject shift and object shift remain remarkably stable over time. To a large extent, variation in subject shift and object shift observed in the baseline is transmitted across generations in American Norwegian; a clear difference is only observed in the limited context of tag questions (see also Anderssen & Westergaard 2020). We suggest that the increase in SV order in American Norwegian is a consequence of pressure to ease processing (see, e.g., Polinsky 2018), although cross-linguistic influence might also be involved. There is little (or no) evidence of change of the underlying syntax of American Norwegian.
