Kaddish is an ancient prayer sequence regularly recited in the synagogue service.
kaddish
There are many. Kaddish is a well-known example.
Most of the Jewish liturgy is traditionally said in Hebrew, although Jewish law permits prayer in a person's native language. The various versions of the Kaddish are in Aramaic, the dominant language of the Jewish community 2000 years ago. In the Jewish liturgy, the Kaddish serves as a Doxology, that is, a liturgical punctuation mark at the end of each section of the service, separating it from what follows.A second unusual feature of the Kaddish is that the most well known variant outside the Jewish community, the Mourner's Kaddish, is said by mourner in memory of the dead, but does not once mention death or mourning. It is purely a prayer of praise.
Here's an example: The Kaddish is the Jewish Mourner's prayer.
It can be at the end of the ceremony.
The kaddish are not a who. The Kaddish is a family of related prayers in the Jewish liturgy. Technically, these are doxologies, that is, short prayers of praise that are used to punctuate longer services, dividing or marking the ends of sections of a service. There is the long Kaddish, the short Kaddish, the Kaddish after study, and the mourner's Kaddish. The latter is a relatively short Kaddish reserved to be said by mourners (if any are present).
Immediate family members recite the Kaddish.
The prayer is called 'the mourner's kaddish'.

Which one? There are lots of them. The Amidah (the standing prayer) is the central prayer of every Jewish service. It is clearly ancient. The various Kaddishes that punctuate organized Jewish worship, serving as doxologies, are ancient. The Shema (Hear oh Israel ...) is even more ancient, as is the Baruch Shem Kavod (Praise the Holy Name) response to the Shema. Another candidate is the Priestly Benediction (May the Lord bless you and keep you ...).
