Metaphor, mostly considered a highly decorative linguistic element of language, has been proved to reveal a natural connection, on one hand, between language and human thinking in general, and, on the other hand, between language use and individual thinking in particular. These features of metaphor will allow us a better understanding of human though in all fields of our reality. The current paper focuses on the field of education to study the roles of metaphor in the reality of the human activity through a combination of a diachronic and a horizontal approach. It aims to introduce three dimensions of the role of metaphor in the field. During the presentation the meta-analysis of the three dimensions of metaphor application in education, that is 1) Dissemination of thought, 2) Clarification of thought, and 3) Research on thought will be completed. Based on professional literature and practical evidence, a comparative method will be applied to highlight the similar and different features of metaphor use in the history of, and in contemporary education practice and theory. The study of the dimensions will be completed through the description of underlying principles and supporting scientific background to analyze the aspects of metaphor application, illustrated with examples. The paper arrives at the conclusion that the application of metaphor in education has been with us for thousands of years, and, as a consequence, based on its fundamental feature of high efficiency in social interaction, its application has become multidimensional.
