The contact-based emergence of the subject-focus construction in Wolof A dynamic perspective

In this article, we focus on the origin of the Wolof subject-focus construction (SFC) from a dynamic perspective. In Wolof, argument focus is expressed morpho-syntactically by means of copulaless cleft constructions consisting of the juxtaposition of the focus and a free relative clause. The free relative clause is headed by a determiner, which takes the form a in the case of the SFC. The determiner a is not found anywhere else in the language outside of SFC. We hypothesise that Wolof borrowed its SFC from Berber languages. The sociohistorical scenario, based on oral tradition, could have been the emergence of Wolof, as a crucible of contact between peoples of diverse origin including Berber groups. This finding is strengthened by the occurrence of other elements common to Wolof and Berber languages, such as clitic attraction, negation, copula insertion, as well as a number of lexical parallelisms.
