TRANSEPT

The Transept is a  rectangular space inserted between the apse and nave in the early Christian basilica. It sprang from the need of procuring sufficient space for the increased number of clergy and for the proper celebration of the service. The bay at which the transept intersects the main body of the church is called the crossing. The transept itself is sometimes simply called the cross.The length of the rectangle either equals the entire breadth of the nave, , or it exceeds this breadth more or less, so that the transept extends beyond the walls of the nave. The transept generally terminates towards the north and south in a straight line.

APSE

The Apse is a semicircular or polygonal termination to the choir or aisles of a church. It is that part of the church where the clergy are seated or the altar placed. It was so called from being usually domed or vaulted, and was so used by the Greeks and Romans. The term is sometimes applied to a canopy over an altar; a dome; the arched roof of a room; the bishop's seat in old churches; a reliquary; a recess, semicircular in plan, covered over with a vault in the shape of a semi-dome or any other description of roof. The apse is always solid below though generally broken by windows above.

AISLE

The Aisle is a lateral or longitudinal divisions of a church, separated from the nave (sometimes called the centre aisle) by rows of piers, pillars, or columns. The term is popularly used to describe the passage between pews or seating. Sometimes a church has one side-aisle only. Often the aisle is continued around the apse. Occasionally the aisles stop at the transepts. The aisle is generally one story, but occasionally there is an upper story, sometimes used as a gallery. As a general rule, churches are divided into three aisles, but there is no fixed rule that governs the number.
