This thesis focuses on issues related to misunderstanding and communication within the teaching of French as a Foreign Language. From the outset, a double question arises: first, how is communication considered in the teaching of FFL? And secondly: what can we oppose this “all-communicative” view? How else could the teaching of a foreign language be opposed to this dogmatic conception of communication?It appears that there is in the current teaching of languages an obsession with communication and a simplified view of language exchanges. Is there not today in the teaching of French as a Foreign Language a misconception about communication, both about how it is viewed and the prominent place which it is given?Rather than concentrating as usual on the learners’ ability to transmit information from one pole to another, it is the aim of this work to propose another perspective taking greater account of the subject and his entanglement in the languages. Without doubt it would be profitable for French as a Foreign Language to consider further the relationship between a subject and a language rather than the communication relationship transmitter-receiver or statement-recipient. Maybe we should take greater consideration of the crucial relationship that is built between a language from elsewhere and a subject incorporating in his mind that foreign idiom.
