1 Part of a building, or any feature of a building, projecting from and subordinate to the main, central part. In Classical and especially Palladian compositions the wings are smaller buildings on either side of the corps de logis, perhaps joined to it by means of quadrants or colonnades, and projecting forward to partially enclose a court or cour d'honneur.
2 Part of a building with its roof at right angles to the adjacent main range, as in a hall-and-cross-wing medieval timber-framed house, with the hall-range flanked by one or two wings.
3 Fillet on a moulding.
4 Straight or curved projecting wall at each side and end of a bridge, also the retaining-wall at each end of a bridge to sustain the bank.
5 One of the folds of a double door or screen.
6 Lateral wall of a rectangular Classical temple, or the space between the cell walls and the peristyle.
