Abstract : This research explores the phenomenon of lexical borrowing from English into the Bahraini Arabic dialect. For that purpose, 166 English loanwords in Bahraini Arabic have been compiled for linguistic analysis. In this study, we investigate the different semantic domains of these words. Moreover, we explore the phonological processes that English loanwords in Bahraini Arabic undergo in the adaptation process. Furthermore, this study also examines the morphological adaptations that these words go through when adapted to Bahraini Arabic. Additionally, it explores the semantic changes English loanwords undergo in the process of lexical borrowing into Bahraini Arabic. Results indicate that nativization, declusterization, gemination, deletion and pharyngealization are the main phonological processes that feature in the adaptation process. Moreover, according to our morphological analysis, some English loanwords in Bahraini Arabic can undergo the process of pluralization showing both regular pluralization pattern -a:t as well as some irregular patterns. Gender assignment was also a feature that English loanwords in Bahraini Arabic undergo. One of our primary results show that nouns are the most dominant grammatical category to be borrowed from. Loan verbs, adjectives and adverbs are also explored in this study. In terms of semantic features, English loanwords in Bahraini Arabic go through the various processes of transfer, narrowing as well as widening of meaning. Additionally, amelioration and pejoration are other semantic changes that English loanwords in Bahraini Arabic went through.
