The article compares the features of the communicativeverbal behaviour of adults and children within the framework of the concept of “personal space” in the original work and in its translation. It highlights socially and culturally acceptable and unacceptable forms of speech behaviour in relation to the personal space of an adult friend and a small child, reveals the extralinguistic factors that predetermine the specifics of the boundaries of the concept of “personal space” at different ages. In the article, personal space is presented as a continuum of actions, events and assessments, based on a person’s ideas about the world, other people, about himself and his activities. Due to the underdevelopment and subjectivity of the image of the world, the child himself cannot highlight the importance of objects and relationships and needs monitoring, although he himself does not realize it and often does not admit it. In adulthood, personal space and personal integrity are akin to synonyms.
