This article aims at reporting the types of relations between "interagents" belonging to specific social spaces. This relation, based on the elaboration of social and discursive practices, allows to identify the tension's spaces and the help aiming at their resolution. We presented two social spaces with language practices potentially in tension. The first is an observation of the linguistic practices during the children's individualized didactic care presenting a linguistic deficit with behavioral disorders at hospital. The second one is interested in the emergence of the violence verbal at school. This approach allows to illustrate how adults are sometimes induced to use a linguistic structure at the beginning of a tension rise. On the contrary, we can see how the adult's linguistic structure allows to create a space on the conflict situation.
