The term IT INTERSECTS THE NAVE refers to the transept, which is an architectural feature of a church. It is a transverse section that intersects the nave, which is the main body of the church. The transept is usually located at the crossing, which is the intersection of the nave and the chancel. The transept is often used to separate the nave from the chancel, and it can also be used to create additional space for chapels or other features.
