compass | ˈkəmpəs | noun 1 ( also magnetic compass ) an instrument containing a magnetized pointer that shows the direction of magnetic north and bearings (orientations) from it . The use of the compass for navigation at sea was reported from China c. 1100, western Europe 1187, Arabia c. 1220, and Scandinavia c. 1300, although it probably dates from much earlier. Since the early 20 th century the magnetic compass has been superseded by the gyrocompass as primary equipment for ships and aircraft .
