Jew

A person whose mother was a Jew or who has converted to Judaism. According to the Reform movement, a person whose father is a Jew is also a Jew. Although the term is derived from the term "Judahite" (meaning a member of the tribe of Judah or a citizen of the kingdom of Judah), it has historically been applied to the patriarchs, the matriarchs and all of the descendants of Jacob and all converts to their faith.
