The Role of Code-Switching and Multilingualism in Enhancing Business Transactions:

A Case Study of Nakuru Town Open Air Market

Abstract

Studies on language use in informal market spaces have largely examined language preferences and communication patterns without sufficiently interrogating how code-switching and multilingualism function as strategic socio-economic tools to facilitate business interactions. This paper examines the role of code-switching and multilingualism in enhancing business transactions at the Nakuru Town Open Air Market in Kenya. Specifically, the study examines how traders and clients use multiple languages to negotiate prices, establish rapport, overcome communication barriers, and foster inclusivity in a linguistically diverse commercial environment. The study adopted a qualitative-dominant mixed-methods approach involving interviews, participant observation, and audio-recorded interactions among traders and customers in the market. Data were collected from purposively selected multilingual participants comprising traders, customers, and market officials over a three-month period. The collected data were analysed thematically and through discourse analysis to examine patterns of language alternation and their communicative significance in transactional settings. Findings reveal that strategic code-switching between Kiswahili, English, and indigenous languages such as Gikuyu, Kalenjin, Dholuo, Ekegusii, and Luhyia plays a significant role in enhancing mutual understanding, building interpersonal trust, clarifying meaning, persuading customers, and strengthening commercial relationships. The study argues that multilingual practices in informal marketplaces are not merely communicative adaptations but also important socio-economic resources that facilitate trade and social cohesion in multilingual urban contexts. The paper contributes to sociolinguistic scholarship by demonstrating how language choice and code-switching operate as dynamic tools of economic interaction and social negotiation in contemporary African marketplaces.
