Abstract
Due to the variety of their local dialects and accents, Arab learners occasionally face some problems when pronouncing English letters and phonemes. These pronunciation errors are caused by the influence of native language interference. Each language in any part of the world has its linguistic characteristics and rules that control their pronunciation and even word-formation process, which distinguishes them from those of other nations. Modern linguists described this phenomenon as verbal behaviors because, by the end of a special stage of a child's growth, it becomes as constant customs. As a consequence, generations inherit these verbal qualities from their ancient without having any choices to make a linguistic formation in particular. As they work to develop their English language fluency, Arabic ESL students, for instance, face several pronunciation difficulties such as adding or replacing new phonemes that do not exist in the target language. The linguistic differences between Arabic and English usually have a crucial impact on how simply a learner can study to form the English letter sounds.
