In the world of language and communication, terminological phraseological units play an important role, especially in the business sector, where accuracy and effectiveness of communication are key success factors. Terminology, as a special lexical group, enriches the language with special expressions that combine semantic saturation and specialized lexical turnover. Terminological phraseological units act as a kind of «codes» understandable to representatives of a certain field, and are designed to facilitate and speed up the process of communication in a professional environment. Terminological phraseological units are structured expressions, often enriched with historical, cultural and professional nuances. In the business sphere, where even small misunderstandings can have serious consequences, the use of specific expressions becomes an integral part of successful interaction. The purpose of this article is to consider terminological phraseological units in the context of business communication in two languages, Kazakh and English, identifying their role, features of use, and also compare their impact in the context of cultural and linguistic differences. By opening the doors to the world of professional communication, we immerse ourselves in a unique linguistic field where these phraseological units become not only a means of transmitting information, but also the key to successful business in various cultural environments.
