CHANCEL

A 'chancel' is the space around the altar at the east end of a church, often enclosed, for use by the clergy. It may terminate in an apse.
As well as the altar, the chancel usually houses the lectern, the pulpit, the credence table, and seats for officiating and assisting ministers. It may also include the choir.
The chancel is typically raised somewhat above the level of the nave, where the congregation gathers. It may be separated from the nave by a rood screen, a rail, or an open space. In some churches, the congregation may gather on three sides or in a semicircle around the chancel.
The word "chancel" derives from the French usage of ''chancel'' from a Late Latin word ''cancelli'' meaning "lattice" (Online Etymology Dictionary). This refers to the rood screen.
