Metaphorization in a special terminology is one of the main problems in modern linguistics. Traditionally, metaphor is understood as an expression used in a figurative meaning and based on a certain similarity of the objects that are compared. Today, scientists come to the conclusion that metaphorization is needed to transmit new concepts of a special field of knowledge using the available nominative means. In other words, a metaphor becomes a kind of a key to understanding the basics of thinking and the processes of creating mental representations of the world. As a result, the metaphorical terms were selected in the special discourse, and they were based on the similarity of one sign of the concept to create similarities between two different subjects, so the properties of one subject were viewed through the properties of another one. For identification of the professional terms, the following signs were used: physical life of man, his mental and social life, family relationships, etc. According to modern researchers, metaphorical models are embedded in the conceptual system of the human mind, this is a kind of scheme by which a person thinks and acts.
