What are the wings of the main part of a church called?

The wings of the main part of a church are referred to as the transepts. In the architectural layout of a traditional cruciform (cross-shaped) church, the transepts are the sections that extend perpendicular to the nave, which is the central part of the church where the congregation typically gathers. This design creates the appearance of a cross when viewed from above, giving these extensions their significant role in the overall structure.

Transepts often serve specific functions, such as housing additional altars or chapels, and can enhance the church's capacity and spatial dynamics. Therefore, the term accurately describes the architectural component in question, distinguishing it from the other choices, which refer to different parts of a church. The nave is the main body of the church, altars are the places where religious rites are performed, and pews are the seating arrangements for the congregation.
