Kippa

A kippah, kippa or kipa, also known as a yarmulke, from the Aramaic meaning "fear of the King" (i.e. God) is a hemispherical or platter-shaped cap, usually made of cloth, worn to fulfill the customary requirement held by some orthodox halachic authorities that the head be covered at all times. It is usually worn by men and, less frequently, by women (in Conservative and Reform communities) at times of prayer.
