Standard Arabic is actually the language of writing. The speeches made in the media and in some TV series are, in most cases, a literal restatement of visual coding of the language (text written in standard Arabic) in auditory coding (reading aloud the written text). Similarly, everyday Arabic does not have the same coding as Arabic that exists in the media, in books and in Arabic language courses. This gives the impression that the current teaching content is not suitable for a usage outside the language classroom.This thesis 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 proposed analysisshows the weak points in the structure of textbooks now in use. It is based on the criteria of the Common European Framework of Reference for Languages (CEFR) and the skill references of Niveaux pour le français that offer an approach batter adapted to the preparation of the lexicon in recent textbooks of teaching moderne languages. This 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.
