Abstract: Reading, writing, listening and speaking are the four primary and required skills of every language. Of the four skills of a language, speaking is the skill that always matters the most for a language learner, and it is considered essential. According to Nazara (2012), speaking is an important and essential skill of the four language skills, and as an EFL student, one needs to master the speaking skill. However, the majority of Afghan EFL undergraduates face difficulties in this all-important skill of the language. According to Zia and Sulan (2015), for most of Afghan undergraduate EFL learners, reading and writing are easy, but in oral communication, they are not accurate and fluent. Hence, this study was conducted to investigate the factors that affect the Afghan EFL undergraduates’ speaking skill at Sayed Jamaluddin Afghani University Kunar, Afghanistan.
