Co-semiosis and other interpersonal activities
This chapter discusses interpersonal activities which have the potential to feed into conventionalization and entrenchment. Co-semiosis is the most important interpersonal activity. It is defined as the negotiation of the mutual belief of mutual understanding and shared intentionality. It is based on the licensing potential of utterance types. Co-adaptation is the tendency to repeat and adopt aspects of the speech or style of others in a usage event. It is also known as accommodation, alignment, persistence, etc. Arguably, co-adaptation has a strong potential for the conventionalization and entrenchment of all kinds of utterance types. Co-construction is another important interpersonal activity closely related to the negotiation of shared intentionality. Further interpersonal activities which are important for the conventionalization of utterance types and the entrenchment of patterns of associations are turn-taking and illocutionary and perlocutionary acts, mitigating, stance-taking, and acts of identity, i.e. self-presentation and positioning.
