“…While these studies document limited, bilateral, phonological accommodation, they also expose a persistent qualitative and quantitative ethnolinguistic divide. This study focuses on one morphosyntactic feature, copula absence, which has been studied extensively as a diagnostic variable in ethnic U.S. varieties (e.g., Labov, 1969;Wolfram, 1969Wolfram, , 1974aWolfram, , 1974bFasold, 1972;Feagin, 1979;Baugh, 1980Baugh, , 1983Bailey & Maynor, 1985a, 1985b, 1987, 1989Rickford, 1997Rickford, , 1998Rickford, , 1999, varieties spoken by transplant communities (e.g., Poplack & Sankoff, 1987;Walker, 1999), and creole varieties of English (e.g., Holm, 1984Holm, , 1988Rickford, 1987Rickford, , 1999Rickford, , 2000Rickford & Blake, 1990;Winford, 1992Winford, , 1993Weldon, 2003). 2 Despite the amount of research on the copula and its near-canonical status in variation studies, it remains a controversial feature both synchronically and historically.…”
