摘要：It is widely acknowledged that English has become the language of communication internationally (Yahya, 2012; Pennycook, 2014). To the researchers’ best knowledge, no research has reported on neither the difficulties non-English major professors face when using English as their formal language of instruction nor on the impact of these difficulties on their professional development. Thus, this paper aims to offer a better insight into the different problems that university professors non-major in English specifically face when communicating in English and their influence on their academic and professional advancement. Non-English major professors need to be competent in communicating English because they need to contact international organizations for publications, introducing partnership, present up-to-date findings in their fields and so on. The sample of the study comprised of 20 non-English major lecturers randomly selected from Hashemite University.

In light of these findings, the paper concludes with some of the participants’ suggestions to solve these difficulties
