This study examines the main features of phonology and morphology in order to determine how understanding of these features contributes in the acquisition and teaching of a second language. The current study successfully establishes the major functions of phonology and morphology in second language training, as well as knowledge of these two disciplines.

Introduction The main focus of this study will be the analysis and understanding of the role of Linguistic Awareness in Second Language Learning, specifically the roles of phonological awareness and morphological awareness, paying attention on which linguistics theories might affect language acquisition and why this happens. The present analysis is divided into four main chapters, 1) a brief literature review on the Second Language Learning, 2) an in-depth overview of phonology and phonological awareness, 3) morphology and morphological awareness and 4) a summary of the roles the disciplines have and the findings of the research. 1.1. Motivation of the study The main premise for this study is the assumption that prior knowledge of a language must influence second language learning. Previous research has already proven that linguistic awareness benefits SLA [1] therefore the goal of this research is to compile a comprehensive summary of what roles phonology and morphology have in Second Language Learning. 2. Literature review The current research focuses on two main topics, Second Language Learning and Linguistic Awareness, it is then appropriate to provide a brief definition on both matters to ease the reader into the main analysis. 2.1. What is Second Language Learning When talking about Second Language Learning, scholars refer to the process of teaching and learning a language that is not native to the speaker [2] . This process is also known as Second Language Teaching, Foreign Language Learning and Foreign Language Teaching. Nevertheless, the meaning remains unvaried. From now on, Second Language Learning will be shortened to SLI for convenience.
