What's the difference between i.e. and e.g.?
"part of a church reserved for the clergy," early 15c., from Church Latin presbyterium, from Greek presbyterion, from presbyteros "an elder" (see Presbyterian). Meaning "body of elders in the Presbyterian system" is recorded from 1570s.
in Western architecture, that part of a cathedral or other large cruciform church that lies between the chancel, or choir, and the high altar, or sanctuary. As an element of a cruciform church (i.e., one laid out in the shape of a cross), the presbytery may be located geographically west of the sanctuary and east of the choir. This area, which is sometimes also called the presbyterium, can be occupied only by members of the clergy, those priests who participate in services within the sanctuary. The presbytery is often raised a few steps above or otherwise separated from the chancel, as in Winchester and Salisbury cathedrals in England, but it may also be combined with the chancel, as in the English cathedrals of Lincoln and York. The term is also used to describe the house of a priest.
