The term metacommunication is best defined as: "interpersonal bridge between verbal and nonverbal communication".
When meta-communication happens, the words talked are regularly customs and contain next to no significance. The expression "meta-communication" was designed by Gregory Bateson in 1970s. Bateson's concept of meta-communication is that some non-verbal communication and idiosyncrasies consolidate with individuals' words to end up codes. Viably conveying along these lines requires that all participants know and see each others' codes.
