Pennsylvania is officially a "Commonwealth," an Old English word meaning the "common weal" or well-being of the public. All Pennsylvania legal processes are carried out in the name of the Commonwealth, although the word does not appear on the State Seal. (Pennsylvania is one of four U.S. commonwealth States. The others are: Kentucky, Massachusetts and Virginia.)
