Debunking Rhaeto-Romance: Synchronic Evidence from Two Peripheral Northern Italian Dialects

This paper explores two peripheral Northern Italian dialects (NIDs), namely Lamonat and Frignanese, with respect to their genealogical linguistic classification. The two NIDs exhibit morpho-phonological and morpho-syntactic features that do not fall neatly into the Gallo-Italic sub-classification of Northern Italo-Romance, but resemble some of the core characteristics of the putative Rhaeto-Romance language family. This analysis of Lamonat and Frignanese reveals that their conservative traits more closely relate to Rhaeto-Romance. The synchronic evidence from the two peripheral NIDs hence supports the argument against the unity and autonomy of Rhaeto-Romance as a language family, whereby the linguistic traits that distinguish Rhaeto-Romance within Northern Italo-Romance consist of shared retentions rather than shared innovations, which were once common to virtually all NIDs. In this light, Rhaeto-Romance can be regarded as an array of conservative Gallo-Italic varieties. The paper concludes with a discussion of the geo-sociolinguistic properties of the two peripheral dialect areas under investigation that lead to a conservative linguistic behaviour within the Lamonat and Frignanese speech communities. Given the relatively similar historical and geo-political background of these speech communities, we attempt the formulation of a geo-sociolinguistic model of linguistic innovation diffusion that captures the conservative behaviour of Lamonat and Frignanese. We propose that those dialect areas that, in Bartoli’s (1945) geo-spatial linguistic typology, are both “lateral” and “isolated” deflect linguistic innovations. This proposal must be interpreted within a more general “gravity” and “wave” sociolinguistic model of diffusion of linguistic innovations, whereby “lateral” and “isolated” dialect areas give rise to a mechanism that we call “the pond rock effect” and that renders such dialect areas resistant to language change.
