Abstract
Individual reports of language history, use, and proficiency are generally considered sufficient for language profiling. Yet, these variables alone neglect the contribution of contextual linguistic diversity to one's overall language repertoire. In this study we used the Contextual Linguistic Profile Questionnaire to evaluate whether there is a difference in contextual linguistic diversity between participants across the linguistically dissimilar contexts of South Africa and England. We further assessed whether self-reported lingualism status groups (monolinguals, bilinguals, multilinguals) scored differently on contextual linguistic diversity to evaluate the utility and uniformity of categorical labels across varying contexts, and investigated how codeswitching and socio-economic status contributed to these effects. Our results demonstrated that contextual linguistic diversity differs between nations: South Africans score higher, promotion of multilingualism is dependent on socio-economic status only in England, lingualism status is not contextually comparable when measured categorically, and codeswitching accounts for linguistic features of South Africans.
