This book throws light on Psycholinguistic as an interdisciplinary field where both fields of Linguistics and Psychology complement each other. Psycholinguistics sets down mental processes involved in connecting Language with thinking at the same time of acquisition (such as the processes through which the mind connects a form with a meaning by way of a Language system). It also introduces processes through which one acquires a system of a Language and follows that system. This book proves that acquisition of second Language requires both psychological factor carried out by Explication and Induction and sociological factor (class room). As to applying second Language, Hebrew is taken as an example. It is also a good opportunity to pour out my experience of learning Hebrew in Ein Shams University ( B. A. ) and London University ( PhD). Hence teaching Hebrew as well as Syriac and Aramaic in Arab universities.
