Since culture is an integral part of the language, teaching and learning of any existing language, require familiarization with its culture. Indeed, words, behaviors, gestures and mimicry as well as customs and habits of each nation find their origins in its culture; from which derives the diversity of the societies since the unmemorable times.It is by learning a foreign language that one discovers a new world whose values and principles differ from those of his/her own milieu. The new world is first presented to the learner through language teaching methods and, then, progressively, he/she becomes familiarized, with the foreign culture. In this article, the study of the term “culture" and its sub-groups is briefly reviewed from the anthropological, sociological and language teaching point of view. After a short outline on the role of the culture in human being’s life, the importance of this topic is examined in language methods, without forgetting to underline the key function of teaching with regard to the transfer of the foreign culture to its public. Also the article emphasizes the sensitive and key role of the teacher in transferring the foreign culture to the learners, as his/her main duty is to create a relationship between foreign and national culture, a relationship which advocates neither xenophilism nor xenophobia but offers a logical and moderate view point to the learner.
