christopher-alexander tells about language that is complete when they are morphologically complete and functionally complete. morphologically complete means that it can stimulate the imaginal into a complete felt-sense so there no gaps. functionally complete means all self-generating forces are internally resolved, so it stays structurally coherent. meaning no erosion. this is a sense that is also an ethical stance
In many ways this is the practice of pragmatic-imagination, filling gaps until a complete language is encountered.
