The nave (/nv/) is the central part of a church, stretching from the (normally western) main entrance or rear wall, to the transepts, or in a church without transepts, to the chancel.[1][2] When a church contains side aisles, as in a basilica-type building, the strict definition of the term "nave" is restricted to the central aisle.[1] In a broader, more colloquial sense, the nave includes all areas available for the lay worshippers, including the side-aisles and transepts.[3] Either way, the nave is distinct from the area reserved for the choir and clergy.[1]
