Abstract: Background: The Parametric Comparison Method (PCM) is an innovative tool for language comparison that strives to reconstruct linguistic phylogeny and to provide new linguistic taxonomies relying on the notion of syntactic parameter (Longobardi 2005; Longobardi & Guardiano 2009, 2017; Guardiano et al. 2020, i.a.). To achieve this goal, the PCM is grounded in the Modularized Global Comparison (MGC), testing an indefinite parametric database across an unrestricted language inventory within a single domain (Longobardi 2003). Over the last twenty years, studies primarily involved the nominal domain, releasing a list of 97 parameters tested on 69 languages across 13 language families (Crisma et al. 2020). This presentation, rather, delves into an unexplored syntactic domain, the complementizer phrase (CP), selecting a language sample of Italo-Romance varieties spoken in various regions. The goal is twofold: first, proving that the PCM does not exclusively function with the nominal domain, but can also be successfully expanded to other structural modules, provided that an effective parametric database is built, second, investigating and categorizing the greatly recognized micro variation in Italo-Romance varieties through a trustworthy parametric tool capable of depicting minimal variational patterns and offering a revised taxonomy. Building the Parametric System: The formulation of a parametric database regularizing the CP was framed with the cartographic approach (Rizzi 1997, i.a.). Each head of the split-CP is independently treated to detect the most salient patterns of variation and the respective parameters regulating them. Broader phenomena (e.g. the realization of a clause-type, the occurrence of a discourse-type exponent etc.) are mapped with core (macro-)parameters, which frame more detailed (micro-)parameters expressing fine-grained patterns of variation (e.g. the operation involved in the realization of clause type, the syntactic nature of the items involved etc.). The core parameters were constructed according to a parameter schema (Longobardi 2005; Gianollo et al. 2008) asking whether a feature F is grammaticalized, checked, spread or strong. Therefore, it was necessary to retrieve a bundle of universally definable features and verify whether these operations occur. The selection of the feature analysed for each head shows a clear deviance from Rizzi (1997) who postulated a one-to-one association between a functional feature and a functional head. Once the core featural-driven parameters, regulating major structural-building operations, were established, other parameters, which regulate salient patterns of variation, were framed within them. The valuation of parameters in the schema sheds light on other structural phenomena, whose (micro-)parameterization is contingent on the value assigned to the parameters in the schema, displaying a significant cross-linguistic variation among the languages tested. In total, 97 parameters were produced and tested.
