Résumé:
After observing the handicaps that stands in the process of teaching / learning of French in the Algerian learners fifth grade, who are new to the language while they lack a sufficient background that lexical allows them to apply their knowledge in works in real communication situations. Face communication situations they are faced with a considerable lack in vocabulary to understand or speak while remaining passive and inert. Interested in the place of vocabulary in the teaching / learning of French, our hypothesis is that the process of teaching / learning vocabulary adopted in the 5th grade class allows the acquisition of this important language. We first recalled some basic concepts related to vocabulary, then we explained the process of teaching / learning it. We then analyzed during and vocabulary exercises in the official program of the 5th grade. We observed at the end of sessions during vocabulary with teachers and students of the fifth year. Finally, we conducted a comparative analysis of the results of the proposed assessment to students. This approach has led us to conclude that the process of teaching / learning vocabulary adopted in 5th year class allows more or less satisfactory control of this part of the language, which is considered as the gateway through which the initiation any living language.
