The Deuterocanonical books of the Bible are books considered by the Roman Catholic Church and Eastern Orthodoxy to be canonical parts of the Christian Old Testament but are not present in the Hebrew Bible. The word deuterocanonical comes from the Greek meaning 'belonging to the second canon'. The etymology of the word is misleading but it does indicate the hesitation with which these books were accepted into the canon by some. Note that the term does not mean non-canonical despite this it has sometimes been used as a euphemism for the Apocrypha.
