“…Using forms of be as an example, these marking options include mainstream overt expressions (i.e., I am, you are, she is, I was, they were), nonmainstream overt expressions (i.e., they is, we was), and nonmainstream zero expressions (e.g., he Ø, you Ø). In the AAE and SWE varieties studied here, and as shown by the examples, the nonmainstream overt expressions are limited to are and were contexts, and the nonmainstream zero marked expressions are limited to is and are contexts (Roy, Oetting, & Moland, 2013). 1 On the basis of these findings, AAE and SWE can be described as presenting structural overlap that makes it impossible to determine if utterances such as They was driving or You Ø coming with me were produced by an AAE or SWE speaker.…”
