The term meta-discussion means a discussion whose subject is a discussion. Meta-discussion explores such issues as the style of a discussion, its participants, the setting in which the discussion occurs, and the relationship of the discussion to other discussions on the same or different topics. It is one of many terms based on the inferred meaning of the " meta-" prefix. The etymology for the prefix dates back to use of Metaphysics as the title of the treatise by Aristotle that came after his works on physics in the traditional ordering of his books. The fundamental meaning of the prefix in Greek is simply "after." The modern, inferred meaning of a higher-order, self-referential consideration of the nature of an activity—rather than actual, first-level participation in the activity—has led to many neologisms such as meta-wiki.
