This paper demonstrates the role of logosphere in strengthening social bonds. In a broader sense logosphere is the layer of the word in human environment, both within mediosphere and outside it. It occurs in symbiosis with the remaining environment layers, i.e. iconosphere, sonosphere, and galenosphere (the layer of silence). In a narrower meaning logosphere occurs when it is organized by the people who form it (family, school, orphanage, etc.). The basic properties of such logosphere involve: the primacy of the word, dialogicity, and its environmental character. Reflection on these properties leads to a conclusion that their functioning contributes to the enhancement of social bonds linking the participants of logosphere.
