This paper is intended to be a contribution to research of communication formations that are shaped by systematic communication. The approach of the author is based on the idea that the human being has a gift for making signs and people make use of this property if they are adapting to a situation of recurrent coexistence. This property enables the participants of such a situation to create social signs with the structure sociolect as the form of the sign: the semantic interpretation of this form as the meaning of the sign. One way of analysing this meaning is by looking at the foundation of the motivation of animal and human behaviour. The author argues that this meaning is based on a feeling of safety and the participants of potential communication formations follow the principle of coordination in order to sustain this feeling and to introduce the state of communication comfort.
