Language Maintenance in Business Interactions: An Appraisal of the Ngambaye and Chadian Arabic-Speaking Communities in Moundou

Abstract

Linguistic communities from northern and southern Chad have interacted through trade for decades, and each has had to find its own way of holding onto a mother tongue while doing business across ethnic lines. This article looks at how that balancing act plays out among Ngambaye and Chadian Arabic speakers in Moundou, the economic capital of southern Chad. Drawing on Fishman's (1991) graded intergenerational disruption scale, we examine how traders, entrepreneurs, and customers choose and switch between Ngambaye and Chadian Arabic in markets, transport, and informal trading spaces. The study is qualitative, built on interviews and participant observation, and asks how language choice connects to ethnic identity, economic opportunity, and social integration.

Ngambaye still dominates within the Ngambaye community itself, where it functions as a marker of cultural identity and solidarity. Chadian Arabic, meanwhile, has become the working lingua franca of the marketplace, the language that lets traders reach across ethnic lines and build wider business networks. Most speakers move fluidly between the two, adjusting to a customer's background, the type of transaction, and the setting (Thomason, 2001); this code-switching keeps commercial relationships running smoothly without forcing anyone to give up their own language.

Business in Moundou, then, sustains Ngambaye even as it feeds the growing reach of Chadian Arabic. Neither language is pushing the other out; they occupy complementary roles that mirror the city's multilingual makeup and the practical strategies its residents have worked out for themselves. We argue that this coexistence rests on a strong sense of community identity, on transmission across generations, and on the simple fact that multilingual competence continues to pay off in everyday trade.
