Metaphor, as a conceptual and cognitive tool, plays an important role in language learning and teaching. It was once thought to be a stylistic problem, but now it is recognized as an essential part of both ordinary and specialist language and, more significantly, as a basic process of how people conceptualize the world. The use of metaphor in language, thought and communication has been examined in second language (L2) learning. The present paper examines roles of using metaphor in language learning and teaching. First and for most, this paper aims at shedding light on a new facet of Gardner’s (1983) multiple intelligence that is metaphoric intelligence. Second, it focuses on the overall history of its utilization in language learning and teaching. Third, a plethora of strategies and activities for its implementation will be discussed in details. Last but not the least, some problems of its application and justification of its implementation will be touched upon.
