Abstract
This paper observes the social relations in interaction, the negotiation of participant's positions in dialogue. Through the communicative practices (e. g. category work, ascribing the roles, activities and stance setting) the speaker takes position and sets positions, which both need to be ratified from others.
If the previous speaker has proposed the submissive position to the next one, the next speaker could change his position thanks to his own consequent communicative activities. The efficient communicative strategy seems to be the rejection of pre-given position and new self positioning (e.g. through reformulation of previous speech).
The appropriate communicative activity to get supremacy over the discourse seems to be evaluation of previous speaker and his speech.
