KyreA derivitive of Kyriahe (don't know how they spelled it), you know, from that song back in the 80's.
The 80s song was called "Kyrie" (by the band Mr. Mister--yes, I still own the album "Welcome to the Real World"). It comes from the Greek expression kyrie eleison, which means "Lord have mercy." It is used in both Orthodox and Roman Catholic religion, where it is a section of the Mass.
