The paper summarises research findings concerned with the study of functional and cognitive properties of multifunctional sentence components used in the framework of business communication, as well as their actualisation in the context of the speaker's linguistic identity. While such components appear understudied, they largely shape the linguacultural profile of a given language. Therefore, a study promoting accurate perception of their properties may lay the ground for a better and more productive intercultural business interaction. The study considers language units functioning at different levels in English, French and Russian to single out the types and functions of syntactic relationships registered in these languages, as well as the means of their expression. The study shows that as far as syntactic constructions featuring multifunctional coordinating components are concerned, their specifics is manifested not only in the set of coordinating means, but also in the peculiarities of their functioning.
