Clitic Climbing and Presuppositional Negative Markers in Occitano-Romance Verbal Complexes. Exploring the Crossroads of Micro-Syntactic Phenomena

In this paper we propose that verbal clusters with restructuring verbs contain a defective embedded clausal boundary. Additionally, this paper constitutes a methodological and empirical contribution to syntactic microvariation in Occitano-Romance varieties: we describe the synchronic variation in the expression of presuppositional postverbal negation and the position of clitics in infinitival complex structures. This empirical study contributes to the understanding of the micro-syntax of negation and clitics as independent phenomena. However, the interaction of both phenomena brings to light the structure of three types of verbal clusters: restructuring verbs, non-restructuring verbs and control predicates. Crucially, the data collected highlight that, although clitic climbing and embedded presuppositional negation are independent phenomena, they can both be explained by the transparency of the embedded clausal boundary. We claim that restructuring verbs select for a defective embedded C/T. Ultimately, the article shows how the comprehension of phenomena in closely related varieties allows us to better understand the architecture of grammar.
