“…The regularization of paradigmatic verb forms is among the best-studied processes in English variationist sociolinguistics (Chambers, 2009; Tagliamonte, 1998, 2012; Wolfram & Schilling-Estes, 2003). Leveling of past be to was represents a vernacular universal in English, also called “default singulars” (Chambers, 2004:128) that belong to “the grammatical processes [that] recur in vernaculars wherever they are spoken” (ibid., 127), and is documented quantitatively in synchronic and diachronic varieties (Anderwald, 2001; Britain, 2002; Dubois & Horvath, 2003; Hay & Schreier; 2004; Hazen, 2014; José, 2007; Schreier, 2002; Tagliamonte, 1998; Tagliamonte & Smith, 2000). Past be variation is context-sensitive and sociolinguistically diagnostic, occurring more frequently in rural and working-class varieties (e.g., Alabama: Feagin, 1979; Sydney: Horvath, 1985; North Carolina: Mallinson & Wolfram, 2002; or West Virginia: Hazen, 2014).…”
