The mechanisms for both are safely housed within our thick protective skull covering. This bond is an unconscious one . We do not have to consciously think about where to put our tongue when we talk. We do not even have to think at all about our breathing, swallowing, talking, and laughing, it is totally automatic.

Language is the brain activity used in communication.
Language is comprised of expressive and receptive skills or talents. The attending skills of looking and listening would be receptive language. The skills of talking or gesturing would be expressive language. Reading silently, would be receptive language and writing to someone would be expressive language. Each of us understands far more than we express .
