“The black men has wives and Sweet harts [and third person plural -s] Jest like the white men”: Evidence for verbal -s from written documents on 19th-century African American speech

Abstract
The analysis of letters written by 19th-century African Americans shows constraints on verbal -s marking which parallel those found in the writing of Scotch-Irish immigrants in the same time period and region, specifically a subject type constraint and a proximity to subject constraint. This correlation is highly suggestive for the study of the development of African American Vernacular English (AAVE). This study finds no support for a basis from a creole or from Standard English for AAVE in verbal concord and concludes that some, perhaps many, African Americans used varieties of English with little or no creole influence. Earlier studies have assumed that standard dialects of English constituted the superstrate in colonial and antebellum America; this analysis makes it clear that we must examine the features of the local varieties, black and white, before making any claims about the influences of language contact on a given variety. Further, the consistent patterns of inflections found in this study show that written documents, in particular letters written by semiliterate African Americans, are a good source for further linguistic study of 19th-century language.
