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.
