Kyrie

Kýrie is from the Greek word κύριε (kyrie), the vocative case of κύριος (kyrios), meaning O Lord. It is the common name of an important prayer of Christian liturgy, also called Kýrie, eléison which is Greek for Lord, have mercy.

Anyone attending a church service in the Eastern churches (whether they be Eastern Orthodox, Oriental Orthodox or Eastern Catholic), will find the phrase Kýrie, eléison (Greek: Κύριε ἐλέησον) or its equivalents in other languages to be the most oft-repeated phrase.
