Abstract
The article considers the scheme of languages functioning in speech and communicative activity of an individual. The key idea is that a person who speaks different languages uses them to a certain necessary minimum. A systematic analysis of the content of each language in the activity of an individual will allow you to determine the boundaries and scope, taking into account the need for communication. Such modeling of a person's needs in languages will ensure the effectiveness of the development of their multilingualism. The content of each model is implemented by applying the achievements of modern linguistics.
