In Bible study, the term Apocrypha refers to sections of the Bible that are not sanctioned as belonging to certain official canons. In some Protestant versions, these sections appear between the Old and New Testaments. More generally, the word refers to writings or statements whose purported origin is in doubt. Consequently, the adjective apocryphal describes things like legends and anecdotes that are purported to be true by way of repeated tellings but that have never been proven or verified and, therefore, most likely are not factual. Both apocrypha and apocryphal derive, via Latin, from the Greek verbal adjective apokrýptein, meaning "to hide (from), keep hidden (from)," from krýptein ("to conceal, hide").
