A wing, or any part of a building flanking another. The term is usually applied to side passages, or lateral division of a church, which are partially separated from the nave and choir by columns or piers. The nave itself, or central part of the church, is sometimes, though improperly, denominated the middle aile. Also spelled 'aile.'
