Alcune riflessioni sui rapporti nel repertorio sociolinguistico

This paper discusses the relationship between language system and sociolinguistic repertoire and also between the different varieties within the repertoire. It proposes to differentiate between the nucleus of the system (i.e. the totality of linguistic elements shared by all the varieties and fundamental for the belonging of a variety to a linguistic system), the 'core' of the repertoire (which represents the sociolinguistic point of reference of the social repertoire) and the 'fundamental variety' (varieta basilare; the variety that constitutes the neutral point of each individual repertoire). These concepts, which assign a foreground position to the distinction between the social repertoire (rooted on his core) and the individual one (rooted on his fundamental variety) is particularly relevant for the study of the relationship between the diastratic and the diaphasic dimensions of variation. In particular the concept of (the) fundamental variety allows to distinguish between a 'first grade diastratic collocation' (given by the diastratic value of the fundamental variety itself) and a 'second grade diastratic collocation' (given by the indidual's potential to move himself amongst different diaphasic varieties).
