The role of English as an official language in Nigeria makes it a necessity for everyone to aspire to learn it as a second language. The Igbo ethnolinguistic group is one of the largest groups in Nigeria. This study sets out to examine the contexts under which Igbo speakers of English violate coda realisation in English words. The objectives of this article are to: examine the patterns of word-final coda violation among the Igbo speakers of English; find out the reason for violating word-final coda; investigate why Igbo speakers of English insert a vowel phoneme and discover the variant vowel phonemes inserted at word-final coda of English words. Findings reveal that the Igbo speakers of English insert a vowel phoneme to open the final closed syllable. The inserted vowel phoneme is not static and the reduction of final complex coda has a specific environment. This article concludes that violation of word-final coda and word-final complex coda among Igbo speakers of English does not render their variety of English unintelligible; rather, it shows that they speak an indigenised form of English which can be referred to as ‘igboglish’ under the umbrella of Nigerian English (‘niglish’).

在尼日利亚，英语作为一种官方语言的作用使每个人都有必要渴望将其作为第二语言来学习。伊博族民族语言群体是尼日利亚最大的群体之一。这项研究着手研究以英语为母语的伊博语使用者违反英语单词尾声实现的情况。本文的目的是：研究以英语为母语的伊博语使用者违反词尾结尾的模式；找出违反字词尾声的原因；研究为什么说英语的伊博语使用者为什么要插入元音音素，并发现在英语单词的最终词尾中插入了变体的元音音素。研究发现，说英语的伊博语人插入一个元音音素来打开最后一个封闭的音节。插入的元音音素不是静态的，最终复杂尾声的减少具有特定的环境。本文得出的结论是，在说英语的伊博语使用者中，违反单词最终尾声和复杂的单词尾声并不会使他们的英语多样性难以理解。相反，它表明他们说的是英语本地化形式，在尼日利亚英语（“ niglish”）的保护下可以称为“ igboglish”。
