Mourners recite this prayer at every service, every day, in the presence of a minyan (prayer quorum) over the course of a year (for a parent) or thirty days (for a sibling or offspring).

Kapparot

An atonement ritual done prior to Yom Kippur. Among certain hassidim, a live chicken (who metaphorically has had transferred to it the family's sins) is swung around the head of its owner before being slaughtered .

Kashrut

Jewish dietary laws. There are many specific regulations, but they cluster around three primary ideas: certain food are forbidden (shellfish, pork, etc.); mixing meat and milk is prohibited; animals must be slaughtered in a specific way which minimizes pain to the animal and all blood must be drained from the animal before it can be cooked and eaten.

The Jewish wedding contract. Traditionally, the ketubah protected the wife in marriage by spelling out the husband's obligations to her and guaranteeing her a financial settlement in case of divorce. Throughout the ages, ketubot (plural) have been illuminated and calligraphed, becoming significant as Jewish art. Today, all manner of egalitarian ketubot are written. Some dispense with the financial and legal aspects, focusing more on the emotional and spiritual sides of the relationship. Others maintain the rabbis' concern with the practical, but define mutual obligations for each spouse.

Kiddushin

The first part of the traditional wedding service in which the groom acquires the bride by giving her a small token, usually a ring, and declaring that she is betrothed to him according to Mosaic law. Today, most non-Orthodox couples have made this ceremony egalitarian, exchanging rings and empowering the bride to speak too. Some, disliking the property aspects of the ceremony, have dispensed with it altogether, substituting a brit shutafut – a partnership covenant.

Kinyan

Lit. Acquisition

In a traditional wedding, the bride is "acquired" by the groom. The kinyan is effected by the giving of a small object, usually a ring. Under traditional Jewish law, a bride cannot acquire a groom -- therefore, this act cannot be made mutual. Liberal Jews have found various ways to work around this dilemma although the Orthodox community, for the most part, does not accept these solutions.

Kippah
A small cap, traditionally worn by men, symbolizing humility before God. Although women traditionally covered their heads with a scarf or hat as a sign of modesty, today, some women wear kippot as well.

Kotel

The Western Wall, which was a retaining wall of the Second Temple, is all that visibly remains of the Holy Temple in Jerusalem. It has long been a holy site for Jews. Since 1967, when the Israeli army recaptured the Old City, including the Western Wall, a large plaza has been created where Jews can congregate and pray. The Wall has also been the subject of controversy, including for women from liberal Judaism, who have been successfully barred from reading from the Torah or donning a tallit at the wall.
