Comunità di pratica, comunità di discorso e comunità testuali tra sincronia e diacronia: alcune considerazioni preliminari

This article outlines briefly the concepts of community of practice, community of discourse and textual community from the perspective of current or possible use in historical sociolinguistics. A brief review of the literature highlights how the tendency to realign communities of practice, on the one hand, and discourse and textual communities, on the other, emerges quite widely in a relationship of inclusive specification: from this point of view, textual communities in particular tend to be understood as communities of practice centred around a text or a textual corpus to which reference is made.
