Linguistic diversity is a defining feature of entrepreneurial environments in postcolonial societies such as Nigeria, South Africa, and India. In these contexts, entrepreneurs routinely navigate multiple language codes within a single communicative act, deploying code-switching and multilingual repertoires not incidentally but as deliberate commercial strategy. This paper investigates the strategic dimensions of multilingual entrepreneurial communication, drawing on Bourdieu's theory of linguistic capital, Communication Accommodation Theory, and Ethnolinguistic Identity Theory as its theoretical foundation. Through qualitative data generated from semi-structured interviews with multilingual entrepreneurs and systematic content analysis of their digital marketing materials, the study identifies five dominant themes: trust and consumer relatability, brand segmentation and register differentiation, digital platform leverage through translanguaging, ethnolinguistic identity alignment, and the management of communicative risk. Findings demonstrate that multilingual entrepreneurs who align their language choices with audience expectations achieve stronger consumer trust, wider market reach, and more distinctive brand identities than those who rely exclusively on dominant metropolitan languages. The paper argues that linguistic flexibility constitutes a form of market capital that should be integrated into entrepreneurship education, business development support, and inclusive digital economy policy in multilingual emerging markets.
