This chapter responds to the questions raised in Chapter 1. It reiterates the need for variationist sociolinguistic analysis of heritage languages to increase our understanding of linguistic structures, variation, and change in multilingual contexts. Each variable is considered through the lens of the profiles corresponding to different sources of change. This allows us to consider whether certain profiles are more common for certain types of variables and of language (types), and whether covariation is more prevalent among any subset of variables. We reiterate how these analyses, based on spontaneous speech in an ecologically valid environment, give a picture of heritage language speakers that contrasts with what we have learned from experimental/psycholinguistic studies, highlighting their stability and consistency with homeland varieties in most cases. Suggestions are made for how this approach can be extended to other under-documented, endangered, and smaller languages, along with discussion of benefits of the HLVC methodology to community members, educators and students, and the field of linguistics. The chapter concludes by reporting on students’ positive responses to engagement with the project.

This chapter reports on trends of continuity and divergence within the heritage generations examined and between heritage and homeland varieties. It discusses the degrees of similarities between the varieties in terms of (a) rates of use of innovative forms and (b) conditioning factors in the constraint hierarchy. The three variables examined are voice onset time (VOT, n=8,909), case-marking on nouns and pronouns (CASE, n=9,661), and variable presence of subject pronouns (PRODROP, n=9,190), each in three or more languages. The similarity in rates and conditioning effects across generations for (PRODROP), examined in seven languages, particularly contrasts with findings for this variable in experimental paradigms. Similarly, findings of little simplification or overgeneralization of the case system in three languages stands in contrast to the outcomes of several previous studies. (VOT) shows a drift toward (but not arriving at) English-like values for only some of the languages examined. For each variable, models are presented and interpreted; a table then details which aspects of the analysis contribute to the interpretation of stability and of each type of variation.

The variables examined in Chapters 5 and 6 show little evidence of being used for identity work. That is, they do not show (consistent) effects of ethnic orientation measures or speaker sex. This chapter explicitly contrasts variables that reflect indexicality (correlation to social factors) in homeland varieties to non-indexical variables. We begin by considering three indexical variables in Italian: (VOT) in unstressed-syllable contexts, (APOCOPE), and (R), illustrating the extent to which indexicality is maintained in the heritage variety. We find increasing use of the more standard variant only in (VOT). Furthermore, we find that younger speakers (both in homeland and heritage) favour the non-standard variant. We then compare the variable (R), the contrast between trill (or tap) and approximant variants, in Italian and Tagalog, where it has indexical value in the homeland varieties, to Russian and Ukrainian, where it does not. Finally, we consider two additional indexical variables: Cantonese denasalization and Korean VOT. We conclude by contrasting the behavior of homeland-indexicals in heritage varieties. The presence of indexical value in homeland varieties does not consistently influence outcomes in the heritage varieties.

What should be revitalized? This chapter considers possible targets for revitalization, taking into account factors such as available resources, whether the language is still spoken, in what domains and by whom. Different people in language revitalization movements have different aims and motivations, and choices must be made about what varieties should be prioritized (including elements of language such as topics, registers and vocabulary). The needs and desires of new and old speakers need to be balanced, with compromises between those who want to preserve a ‘pure’ variety of language and what people actually do - particularly new speakers, as the language expands into new domains and new terminology is needed. In the capsules, an activist describes his realisation that for revitalization purposes he needed to give up looking for ‘the pure Wymysiöeryś language’ and start listening to what people were actually saying. Purist attitudes to Spanish influence on Nahuatl are explored, showing how they had counter-productive effects on language survival. Some activists are now starting to encourage young people to create neologisms from within the heritage language.
