Language Contact and Change in Contemporary Nigerian Arabic: A Variationist Sociolinguistic Study

The Arabic spoken in Nigerian scholarly and commercial communities has undergone significant language contact-induced change through sustained interaction with Hausa, Kanuri, Fulfulde, Yoruba, and English over centuries, yet variationist sociolinguistic methods have never been applied to the systematic study of this living Arabic contact variety, leaving its sociolinguistic patterning, variation, and change dynamics uncharted in the literature. This study applies variationist sociolinguistics to the systematic investigation of language contact and change in contemporary Nigerian Arabic, conducting the first large-scale variable rule analysis of phonological, morphological, and syntactic variation in Nigerian Arabic communities in Kano, Maiduguri, Yola, and Lagos. Building a sociolinguistic corpus of 200 speakers stratified by age, education, gender, city, and Arabic learning pathway, the research records approximately 500,000 words of natural speech data and applies variable rule analysis using Rbrul and multivariate statistical techniques to identify the social and linguistic constraints governing variation in five key variables: emphatic consonant realisation, case vowel deletion, broken plural formation, complementiser choice, and negation strategy. The study finds age-grading patterns in case vowel deletion and complementiser choice suggesting ongoing contact-induced change in progress, while emphatic consonant variation is robustly conditioned by educational pathway. Social network analysis reveals that scholars with stronger links to Arab world networks exhibit significantly more conservative Arabic variants.
