In English, the prefix "meta" can indicate "beyond, about", as "meta-economics" or "meta-philosophy" (see meta), inspired by the non-Greek use of the word "metaphysics", which in Greek was just the title of a work of Aristotle, the "Metaphysics", so named simply because in the customary ordering of the works of Aristotle it was the book following the "Physics"; the Greek word thus meant nothing more than "book that comes after book entitled "Physics"". In Greek, composite words that have μετα- ("meta-") as the initial element are most frequently used "of "change" of place, condition, plan, etc.", as in the English word "metamorphosis". Even in a non-religious context, the Greek word μετάνοια ("metanoia"), in particular, meant "change of mind or heart, repentance" or, in rhetoric, "afterthought, correction".
