Commonwealth除了表示熟知的“英联邦国家”（the Commonwealth of Nations）外，在美国，也指代肯塔基州、马萨诸塞州、宾夕法尼亚州和弗吉尼亚州。查阅相关资料发现，Mass.gov介绍马萨诸塞州的历史时有提及“Commonwealth”的由来，如下所示：

“From 1776 to 1780 the words ‘State of Massachusetts Bay’ appeared on the top of all acts and resolves. In 1780, the Massachusetts Constitution went into effect. Part Two of the Constitution, under the heading ‘Frame of Government’ states: ‘that the people ... form themselves into a free, sovereign, and independent body politic, or state by the name of The Commonwealth of Massachusetts.’ Virginia (on June 29, 1776) and Pennsylvania (on September 25, 1776) adopted Constitutions which called their respective states commonwealths. Kentucky is also called a commonwealth in its full official state name (and in the Third Kentucky Constitution of 1850). Commonwealths are states, but the reverse is not true. The term ‘Commonwealth’ does not describe or provide for any specific political status or legal relationship when used by a state. Those that do use it are equal to those that do not. Legally, Massachusetts is a commonwealth because the term is contained in the Constitution.”

从上述描述可以看出，这四个州早在其各自州通过的宪法中就已经使用了“Commonwealth”这个称呼，一直沿用至今。“Commonwealth”可以表示州（state），但是州（state）却不能表示“Commonwealth”。在表示州时，“Commonwealth”并不指代政治地位或法律关系。因此，在文件中遇到“Commonwealth”时，需要联系上下文，辨别文件所指到底是与英联邦国家相关还是与美国相关，若与美国相关，还需进一步辨别究竟指的是哪个州。

例句：
