Introduction

In today’s global society, an increasing number of people speak a very low number of widely spoken languages that enjoy a high level of standardisation, time-dated official recognition and considerable resources. At the same time, minority, local, unofficial, nonstandardised, under-resourced languages are gaining interest from specialists, activists and society as a whole.1 In this respect, diverse labels have been used to describe the countless bi- or multilingual repertoires including at least one minority language. These labels highlight the varying relationships in terms of typological distance between the varieties or languages at issue. Moreover, they highlight the asymmetry in terms of status and power between them.
