This paper highlights the important role of Pidgin in economic development in West Africa. We use a unificationist
model of dependence relations to explain the nexus between West African Pidgin (WAP) and the region’s socio-economic development.
The study draws on the formidable role that Pidgin plays as the language of communication in the thriving informal cross-border
markets along the Nigerian-Cameroonian border. The use of Pidgin is a special case of the general phenomenon of indigenous
languages that serve as vehicular languages of the informal economy in Sub-Saharan Africa. The paper argues that the existence of
WAP as a language of informal economic activities in this region fosters cooperation and social cohesion that plays a role in the
expansion of informal cross-border trade, which is a primary source of household income for the people. The research reveals a
sociolinguistic dimension to the expansion of informal economic activities that are a prerequisite to wealth creation and poverty
elimination. This finding also suggests that Pidgin can be harnessed for an efficient transition from the informal to the formal
economy. Therefore, the paper advocates a region-wide language policy that recognizes Pidgin as a factor in the region’s economic
growth and development.
