Meta

Meta- (from the Greek preposition μετά = "after", "beyond", "adjacent", "self", also commonly used in the form μετα- as a prefix in Greek, with variants μετ- before vowels and μεθ- "meth-" before aspirated vowels), is a prefix used in English (and other Greek-owing languages) to indicate a concept which is an abstraction from another concept, used to complete or add to the latter.
