Grounding in communication (or common ground) is a concept that has been proposed by Herbert H. Clark and Susan E. Brennan and that refers to the "mutual knowledge, mutual beliefs, and mutual assumptions" that is essential for communication between two people. Successful grounding in communication requires parties "to coordinate both the content and process." The concept is also common in philosophy of language.
