In daily language use, we sometimes comment on the conversation with phrases such as "What do you mean by saying that?" or "That was nice of you to say." This communication about the communication is sometimes labeled as metacommunication. It can be used for many different purposes; for instance, to try and clarify or appraise something that has been said in a conversation. In higher education, a recent empirical study finds that discussions between the student and supervisor about the supervision process have a positive impact on the quality of the communication. Despite this, we know little about the specific metacommunicative mechanisms that may be of importance in supervision. One reason is that most definitions of the metacommunication concept are vague and inconsistent. The goal of this paper is therefore to review a broad range of research literature about metacommunication in an attempt to develop a more comprehensive and complex definition. These perspectives are then used to discuss what specific types of metacommunication might facilitate good supervision in higher education. It is suggested that one should distinguish between metacommunication as part of a transparent communication style and metacommunication about the collaboration period in supervision.
