Anachronism

An anachronism, from the Greek ανά (ana: up, against, back, re-) and χρόνος (chronos: time), is a chronological inconsistency in some arrangement, especially a juxtaposition of person(s), events, objects, or customs from different periods of time. Often the item misplaced in time is an object, but it may be a verbal expression, a technology, a philosophical idea, a musical style, a material, a custom, or anything else associated with a particular period in time so that it is incorrect to place it outside its proper temporal domain.
