Definition: Anachronistic means "inconsistent or outdated in comparison to something else, especially one that is not current." This term comes from the Greek words "anar" meaning "to be old-fashioned," and "kristos" which means "time," hence giving us "anachronistic" as "old-timey". The word implies an absence of the latest information or the inability to appreciate or understand something that was more recent in history, such as a technology or concept.
