Kaddish
The Kaddish is an ancient Aramaic prayer used in various ways during prayer and is found in the Jewish prayer book - the Siddur. There are two forms of the Kaddish a shorter "mourner's" prayer and a slightly longer "reader's" prayer. There is also a "half" Kaddish, which is the first half of the reader's Kaddish. The reader's kaddish separates parts of the morning, afternoon, and evening prayers, while the half Kaddish separates smaller divisions within one part.
In addition to these uses, Kaddish is prayed by the men of the family (and other than the family) of the deceased loved one at the time of decease and at the yearly anniversary remembrance (Jahrzeit). Though it is a prayer for the departed, there is no mention of death. It is rather a prayer for the glorification of God who is the righteous judge.
