This value assignment presupposes that e.g. freed is a stative verb (freed is a more acrolectal form than fried). This analysis is supported by the fact that the same is the case in San Andres Creole English and that the item in question combines with the past negator neva. However, as English copulas are becoming more and more frequent in Nicaraguan Creole English, this analysis may no longer hold in the future.
