In this contribution, we look at Arabic borrowings in Tima, a Niger-Congo language spoken in the north-west of the Nuba Mountains (as well as in the Sudanese diaspora). Due to several factors, outlined in the paper, Arab culture has been exerting more and more influence on the Tima way of life, especially with regard to the Tima language, where we find – to varying degrees – Arabic lexemes, phrases and whole utterances. A detailed analysis of the phonotactic and morpho-phonological adaptation of Arabic borrowings is followed by a discussion on the socio-linguistic setting of language contact, i.e. essentially a contact between Arabic and Tima speakers. Eventually, as we argue, a repertoire approach seems the appropriate way to tackle the issue of language use in today’s Tima society.
