There still exists another type of diglossia, which is between the regional languages and the minority languages. Here, we label the regional languages as acrolects while the minority languages as the basilect. In this case, the minority language is spoken only in very intimate circles, like the family or the tribe one belongs to. Outside this circle, one would speak in the prevalent regional language, while maintaining an adequate command of Filipino for formal situations. Unlike the case of the regional languages, these minority languages are always in danger of becoming extinct because of speakers favoring the more prevalent regional language. Moreover, most of the users of these languages are illiterate and as expected, there is a chance that these languages will no longer be revived due to lack of written records.
