Concepts. If you ever get the chance with family or friends, spend some time talking with little kids who haven't been talking long. They *know* what they want to say, but they simply don't have a way to communicate it yet. You don't need to know what "fear" or "dark" is to know you're scared when there's no light. You don't need to know what "happy" or "cake" is to know you like the feeling you get when eating it. The emotions and observations are the same, it's the communication that breaks down without a verbal or visual way to inform others of your position and thoughts.
