Nowadays the ability to discuss complex scientific and technical phenomena metaphorically is considered to be a compulsory faculty for successful professional interaction. It incorporates the ability of communication participants to understand metaphorical meaning construct, trace its implementation in LSP context, and transfer its meaning to other languages, preserving the effect and associations triggered by lexical items based on metaphoric meaning transfer. The paper aims at describing complex organization of metaphorical competence and at investigating its role in the process of professional communication, paying special attention to the differences in application and challenges associated with its use in the multilingual setting.
