How can we describe the ability to communicate an idea in which we cannot describe? We have conversations where we are never fully able to use words to say what we're trying to say. We circle around them, with metaphors and similies, but never say exactly what it is, end the statement with "Do you know what I mean?" and get a yes. Somehow we can come to a consensus on a topic without ever using a clear definition of that which we are speaking. You know what I mean?
