The article illustrates a sociolinguistics of language vitality that accounts for "minority" and unofficial languages across multiple localities in dispersed communities of multilingual speakers of Zambia where only seven out of seventy-three indigenous languages have been designated official and "zoned" for use in specified regions. Using signage and narratives of place from selected rural and urban centres of the City of Lusaka and the City of Livingstone, we show how minority and non-official languages (some of which are unofficial and minor in region, but official in other regions) come to be part of the semiotic landscapes and social narratives of place outside legislated language "zones". We problematize intergenerational language vitality and endangerment frameworks and notions of linguistic performative identities and reciprocal bilingualism to suggest that the presence of "out of place" languages in dispersed communities of speakers in multiple localities is indicative of the vitality of the languages concerned. We conclude that language revitalisation frameworks need to consider alternative ways of language transmission focusing on mobile "multisited" and "delocalised" communities of speakers and their heteroglossic language practices. This means locating the languages or their fragmented forms in the spoken and written repertoire range of dispersed multilingual communities across multiple localities.
