The term 'section of a basilica' can be broken down into two crossword solutions: NAVE (4 letters) and Aspe (4 letters). The NAVE is the main body of a church, usually located at the western end. It is typically the longest and widest part of the church and is where the congregation gathers for worship. The Aspe is the aisle that runs along the side of the NAVE and is often used as a place for processions. It is usually separated from the NAVE by a row of columns or pillars.
