A substantial body of research has examined the role of English in South Africans' linguistic repertoires. Many of these studies have investigated whether a language shift towards English might be underway among first-language (L1) speakers of the indigenous languages. At the same time, the role of English in the repertoires of L1 English speakers has received little attention, the implicit assumption being that English remains dominant for them. This paper presents an empirically informed comparison of English experience within and across L1 and non-L1 (Ln) English speakers in order to shed light on the importance of English in these individuals' repertoires. Cluster analysis is employed to analyze language background data from bi-/multilinguals (n = 200). The analysis produces two clusters, which differ in extent of English exposure and preference for English use. All but one of the L1 English speakers belong to the 'higher exposure, higher preference' cluster, while the vast majority of the Ln speakers fall into the 'lower exposure, lower preference' cluster. The results indicate that English experience is relatively homogeneous across L1 speakers but differs, for the most part, across L1 and Ln speakers. The findings are relevant to our understanding of language use in multilingual South Africa.
