The basis of all communicative processes is the language: it is the sign system that provides the communication process and serves as a kind of reservoir from which the communicative culture feeds on. Language is an imperative of communicative activity, communication par excellence. Language is a key means of realizing the communicative potential, namely: at the level of the language post factum and a posteriori, the communicative potential, firstly, acquires expressive content-functional characteristics, and secondly, it realizes itself in practice. Communication is not a simple process of transferring information from a source to a recipient. Its structure is formed by three elements: communication, information and understanding.
