Null subjects in Middle Low German : diachronic stability and change

Middle Low German (MLG) syntax is still relatively underresearched. One blank spot on the map is whether MLG allowed null arguments, in particular null subjects, and if so, of what kind. As recent research (Volodina 2009, 2011, Volodina & Weiß 2016, Walkden 2014, Kinn 2015) demonstrates that languages closely related to MLG did have null subjects in a form that no longer exists in Modern Germanic languages (Rosenkvist 2009), the current paper positions MLG in this respect. Updating Farasyn & Breitbarth (2016), we present novel data showing that MLG distinguished two different kinds of referential null subjects (RNS). We argue that MLG, while preserving the null-subject property from Old North-West Germanic to a high degree, was already in the transition to a topic-drop language of the modern V2-Germanic type. This paper provides an analysis of the licensing of RNS in MLG and of the factors influencing their occurrence
