Drawing the krtań: Laryngeal alternations in Polish

Polish exhibits the cross-linguistically common processes of final devoicing and voice assimilation. Notably, these target not only obstruents and obstruent clusters, but also certain obstruent-sonorant clusters. This paper argues for an analysis in Harmonic Serialism where sonorants acquire laryngeal nodes, thereby becoming susceptible to the same constraints that act on obstruents. There is an asymmetry between OS#O clusters, which show assimilation, and O#SO clusters, which do not. The analysis captures this asymmetry with positional faithfulness constraints on word-initial sonorants. The analysis also straightforwardly models other patterns in Polish and neatly captures a dialectal difference between Warsaw and Cracow Polish with a single constraint reranking
