This article deals with the problem of the composition of the lexical content of textbooks of teaching Arabic L2 of Higher Language Institute of Damascus (Syria). A content that does not withdraw from standard norms (focus on the adaptation of a classic or moderne standard Arabic), but seeks to be as close as possible to the daily practice of language that is very rich in dialect. The current content represents the traditional approach of the lexicon, which focuses on the semantics of words and phrases while the communicative features of these language elements are little treated. The analysis focuses on finding the crossing points in standard and spoken Arabic in Syria to build a route map that allows the learner an easy passage from what he learns in the Arabic language classroom to Arabic that is really practiced in everyday communications. It provides some solutions to reduce the gap between these two usages of Arabic.
