This study revisits the V3 linearization AdvP>Subject>finite verb in Kiezdeutsch, comparing it to resumptive verb-third Left Dislocation and Hanging Topic Left Dislocation. Using corpus data, preverbal object DPs are shown to almost never occur across verb-third distributions, yet preverbal nominative subjects and spatio-temporal elements are unproblematic. This behavior is argued to involve a low C-domain position encoding a Subject of Predication requirement (see Cardinaletti 2004) tied to aboutness and nominative Case-assigning features, but not a strict D-related subject EPP. Based on comparison with other corpora and analysis of metadata, speakers from non-German-speaking homes, namely successive bilinguals, are argued to have innovated this property. A novel account is suggested for the emergence of V3 based on claims that it results from a natural informational order (Wiese et al. 2020), which is formalized as a Minimal Default Grammar (Roeper 1999) available to children before they fully acquire CP and TP. Children acquiring a V2 language must either reject V3 or incorporate it into a V2 syntax. Lacking adequate counterevidence in their input, Kiezdeutsch speakers do the latter.*
