Radio, in particular, the popular Asante Twi talk-radio format that emerged in the mid-1990s, provides a unique forum for analyzing the linguistic tensions of contemporary Ghana. Radio is a context where talk and debate are central; since language is foregrounded, anxieties and beliefs about what the use of a particular language indexes socially are thrown into stark relief. This paper draws on conversation analysis, information structure, and ethnography to make sense of the prevalence of intrasentential codeswitching into English in the context of predominantly Twi talk-radio debates. It proposes that switches into English mark new or salient information, and as such function as a pragmatic tool in radio discourse, allowing speakers to negotiate the conversational floor and metapragmatically frame the speech event. It is argued that English’s pragmatic force in this context is drawn from its ability to index a multivalent prestige born of contradictory sites of authority within contemporary Ghanaian life.

Capturing the zeitgeist of youthful challenges to the status quo in Ghana, a video of an anonymous young person challenging an older politician with a derisive call of “Tweaa!” went viral in 2014. Reentextualizations of the encounter were soon circulating online in the form of memes, songs, and hashtags and offline in joking exchanges everywhere from vegetable markets to parliament. This article traces the many ironic reembeddings of the tweaa clip across these contexts, as young people used tweaa to subvert and interrogate Ghana’s rigid social hierarchies—ultimately producing an enduring shift in the vocabulary of protest in Ghana. Tweaa, once a casual interjection of disapproval, is now explicitly seen as iconic of the disenfranchised challenging those in power: a verb meaning “to protest inept authority.” This case study of memetic circulation suggests that memes not only discursively produce publics but can effect seismic semiotic shifts in everyday language.
