Cardinal \Car"di*nal\, n. [F. carinal, It. cardinale, LL. cardinalis (ecclesi[ae] Roman[ae]). See Cardinal, a.] 1. (R. C. Ch.) One of the ecclesiastical princes who constitute the pope's council, or the sacred college. [1913 Webster] The clerics of the supreme Chair are called Cardinals, as undoubtedly adhering more nearly to the hinge by which all things are moved. --Pope Leo IX. [1913 Webster] Note: The cardinals are appointed by the pope. Since the time of Sixtus V., their number can never exceed seventy (six of episcopal rank, fifty priests, fourteen deacons), and the number of cardinal priests and deacons is seldom full. When the papel chair is vacant a pope is elected by the college of cardinals from among themselves. The cardinals take precedence of all dignitaries except the pope. The principal parts of a cardinal's costume are a red cassock, a rochet, a short purple mantle, and a red hat with a small crown and broad brim, with cords and tessels of a special pattern hanging from it. [1913 Webster] 2. A woman's short cloak with a hood. [1913 Webster] Where's your cardinal! Make haste. --Lloyd. [1913 Webster] 3. Mulled red wine. --Hotten.

The males have loud and musical notes resembling those of a fife. Other related species are also called cardinal birds. Cardinal flower (Bot.), an herbaceous plant (Lobelia cardinalis) bearing brilliant red flowers of much beauty.
