For general remarks, cf. my comment on the Feature "Urban/rural variation: phonology". Morphosyntax in more basilectal styles differs very much from morphosyntax in more acrolectal styles. In acrolectal styles, the anterior of verbs like ten, ben etc. tends to be tinha, binha (cf. Portuguese tinha, vinha); in basilectal varieties, it tends to be tenba, benba, i.e. regular. In acrolectal styles one may find passive constructions in which the agent is mentioned. In basilectal styles, there is no mention of the agent in passive constructions.
