See below for a great diagram/illustration from David Gray about language, about which he says:
“Language is more than just communication; it is the primary method by which we do things together. Language is the accumulation of shared meaning – of common ground.”
1) One-way communication: message sent
2) Two-way communication: Both sides feel understood
3) Collaboration: Thinking, planning and making decisions
4) Co-creation: Joint activity, making and doing
