Emotioning is fundamental. We are always emotioning. Conversation refers to the flow of emotioning and languaging as they are delicately intertwined. Conversation does not just refer to the spoken interaction, but entails our body movement and expression, touching and so on. What we say and do in conversation does not instruct or convey, nor determine a response - it simply triggers changes in the emotioning and languaging of another, which, in turn, shape the next bit of the conversation.
Meaning arises in the flow of conversation.
It does not reside in words themselves, nor can it be transferred from person to person. The conversations form a network and these networks of conversation constitute our culture . Our culture changes by this process of conversation, mostly amongst small groups of people at a time. Therein lies great hope and also great responsibility for the way we relate to others. A useful set of more detailed definition statements can be found in Maturana's Disciplinary Matrix which is maintained by Rob Sable.
