Non-Verbal Communication

Processes of communication without the use of language proper, e.g., body movements, gesture, smells but also such extra-linguistic features of speech as intonation, speed, pause. Non-verbal communication is expressive and manifest as opposed to being about something outside the communicator. Non-verbal communication tends to provide the context of verbal communication and has the power to disambiguate (but also to invalidate) the content of linguistic expressions. (Krippendorff)
