The present paper aims at catching a glimpse of the process of second language learning and acquisition among adult learners in Romania. When talking about adult learners, the focused age group comprises individuals over 24 years old who are no longer enrolled in any type of educational system. On the contrary, they already have jobs, families and lead a busy life. The paper comprises four parts – the introduction presents some factors, like age, psychological and environmental components, which interact in the process of successful language acquisition. The second part discusses motivation which has a pivotal role in the process of language acquisition while in the next part some difficulties Romanian adult learners face when learning English are presented. The paper ends with conclusions, emphasizing that the process of second language acquisition is not at all a simple one, it is a bouquet of factors which influences the final result.
