This study examines the internal and external constraints on glottal replacement of /t/ among adolescents in London and Edinburgh. Results show that phonological and stylistic constraints play an important role in determining the realizational variation of /t/, as many similar studies have shown. However, there is also clear evidence that our understanding of this phenomenon has been restricted by the limited set of factors that have been investigated previously, as results show that this feature is also constrained by word frequency and morphophonological factors. These findings raise important questions concerning the role of morphological compositionality in language change and the nature of lexical diffusion.

We discuss some apparent limits on the acquisition of variation suggested by our recent work exploring how teenage migrants to the U.K. acquire local norms of variation. We focus on the constraints on the (ing) variable that emerged from a multivariate analysis. We find evidence for a systematisation of the variable among immigrants, involving some linguistically and cognitively predictable constraints, but also the emergence of social constraints not found in the teenage native speakers. We argue that transformation of variable constraints is a necessary artefact of the inherent complexity of sociolinguistic variables, particularly those with social indexicality. This research note: (1) delineates some theoretical and practical questions involved in incorporating social indexing in variationist studies, especially of non-native speakers; and (2) further explores reallocation (transformation) in the study of language contact. Wir behandeln mögliche Grenzen des Erwerbs soziolinguistischer Variation, die unsere jüngste Studie zum Erwerb lokaler Variationsnormen jugendlicher Immigranten in Großbritannien zu zeigen scheint. In unserer Ergebnisdarstellung konzentrieren wir uns auf die Faktoren, die die Verwendung der (ing) Variable beschränken. Die Ergebnisse gingen aus einer multivariaten Datenanalyse hervor. Wir zeigen, dass die Variable unter Immigranten systematisiert wird, was das Erscheinen einiger linguistischer und kognitiv voraussagbarer Faktoren aber auch einiger interessanter sozialer Faktoren einschließt, die nicht unter den jugendlichen Muttersprachlern gefunden werden konnten. Wir zeigen weiterhin, dass die Umwandlung variabler Faktoren ein notwendiges Artefakt der inhärenten Komplexität soziolinguistischer Variablen ist, insbesondere von Variablen mit sozialer Indexikalität. Diese Notiz umreißt einige praktische Fragen in Bezug auf (1) die Einfügung sozialer Indizes in variationslinguistische Studien, insbesondere solcher, die Nicht-Muttersprachler betreffen, und (2) die weitere Erforschung des Prozesses der Umverteilung in der Untersuchung von Sprachkontaktphänomenen.

Variation conferences have provided helpful formative feedback. We alone are responsible for any failings in this paper. The high schools we worked in remain anonymous, but we owe a debt of great magnitude to the staff and students in Edinburgh and London who worked with us on this project. We admire and respect the individuals in these schools for the work they are doing. In particular, our thanks go to the migrant teenagers, for some of whom the interview and reading tasks were a major effort. Wielkie dzieki! 2In recent years, the UK has experienced unparalleled numbers of migrants from Eastern Europe, particularly Poland. Many migrants came with their families. We examined variation in the English spoken by adolescent Polish migrants in Edinburgh and London. We asked: To what extent are teenage Polish migrants acquiring the patterns of variation typical of their local peer group? We compare the results for the well-known variable (ing) in the speech of both Polish migrants and their same age British peers. Our results indicate that the Polish teenagers seem to be sensitive to the overall rates of the non-standard variant in the city they have moved to. Moreover, Polish teenagers also replicate some of the linguistic and social constraints found in the speech of the locally-born teens. In some cases, they partially replicate the constraint patterns found in the locally-born teenagers, and in other cases they introduce novel constraints unattested in the speech of their locally-born peers. The results of our study raise several questions regarding local shared constraints and universal learning tools, potential supra-local constraints and the status of (ing) as a sociolinguistic variable for learners of English. We discuss these in the final section of this paper.

This study examines the lexical and grammatical diffusion of TH-fronting amongst adolescents in London, where TH-fronting is well established, and Edinburgh, where it is a relatively new phenomenon. Our results reveal that the application of TH-fronting is constrained in Edinburgh in ways that are not relevant for London, and vice versa. Specifically, whereas TH-fronting is sensitive to phonotactic context and prosodic position in Edinburgh, we observe no such effects amongst the London speakers. Morphological complexity, on the other hand, is a significant predictor of TH-fronting in both regions; however, we also find evidence of significant gender differences in the use of fronting in London that do not emerge in our Edinburgh data. We argue that these results attest to the more established nature of TH-fronting in London as compared to Edinburgh. We also address the question of how speech perception influences the emergence and spread of innovative neutralisation phenomena like TH-fronting. The results of this study further highlight the usefulness of a comparative variationist approach to understanding patterns of dialectal variation and change.
