A Critical Review of Segmental, Suprasegmental and Sociolinguistic Variation in Nigerian English Phonology

Abstract

Nigerian English has developed as a result of prolonged contact between English and the many indigenous languages spoken in Nigeria. This contact has produced a range of segmental and suprasegmental patterns that distinguish Nigerian English from other varieties of English. This article critically reviews research on Nigerian English phonology, with particular attention to Hausa, Yoruba, Igbo, Ijaw, Ibibio and Edo English. It examines vowel and consonant systems, monophthongisation, consonant cluster reduction, stress, rhythm and intonation, while also considering the influence of first language, region, ethnicity, education and social context. The review shows that Nigerian English cannot adequately be described as a single uniform pronunciation system. Although some features occur across linguistic groups, others are associated with particular regional or ethnic backgrounds. Research on Hausa, Igbo and Yoruba English has provided much of the foundation for the description of Nigerian English phonology, but studies of Ibibio, Edo, Ijaw and other less studied varieties show that the national picture is more complex. Recent acoustic research has further demonstrated that vowels traditionally classified as monophthongs may exhibit substantial internal movement when examined through formant trajectories. The review therefore argues for a multidimensional understanding of Nigerian English phonology in which common national patterns, ethnic and regional variation, individual differences and social factors are considered together. The findings also have implications for pronunciation teaching. An intelligibility-oriented approach can recognise Nigerian English as a legitimate variety while providing learners with the knowledge and flexibility required for communication across different English-speaking contexts.
