Contradaction means: The Portmanteau definition of contradiction is a statement which denies or redacts the combination of several source materials in one work. Contradaction refers to a redaction that ultimately leads or demands a contradiction in previously established facts within one or more source materials. Each type of redaction, except simple merged combinative, is a contradiction because it all causes or requires a contradiction with the facts previously established for one or more original source materials.
