This study aims to investigate a phonological phenomenon that occurs in Emirati Arabic (EA), whereby the voiced palato-alveolar affricate /ʤ/ changes into the voiced palatal approximate (glide) /j/. In particular, this study attempts to determine whether this phonological alternation is triggered by a certain phonological environment, or whether it occurs randomly without any rule. It also endeavours to examine the hypothesis that this phonological phenomenon was borrowed from other Arabic dialects spoken in the Gulf through language contact.
