Kaddish is a Jewish PRAYER and ELEGY that is traditionally recited in memory of the dead. It is a PRAYER of praise to God, and is often used during funerals and memorial services. The term Kaddish is derived from the Hebrew word for 'SANCTIFICATION' and is typically recited by a mourner or a group of mourners. The PRAYER is composed of several sections, including a blessing of God's name, a declaration of faith, and a request for peace. The ELEGY portion of Kaddish is a lamentation for the deceased, and is usually recited by the mourner or a group of mourners. The ELEGY typically includes a plea for mercy and a request for the deceased's soul to be at peace.
