what is the difference between a commonwealth and a state in the usa
Commonwealth (U.S. state) The term "Commonwealth" does not describe or provide for any specific political status or legal relationship when used by a state.[8] Those that do use it are equal to those that do not. A traditional English term for a political community founded for the common good, it is used symbolically to emphasize that these states have a "government based on the common consent of the people"[9] as opposed to one legitimized through their earlier colonial status that was derived from the British crown. It refers to the common "wealth", or welfare, of the public[10] and is derived from a loose translation of the Latin term res publica.[a]
Puerto Rico On February 4, 1952, the convention approved Resolution 22 which chose in English the word Commonwealth, meaning a "politically organized community" or "state", which is simultaneously connected by a compact or treaty to another political system. Puerto Rico officially designates itself with the term "Commonwealth of Puerto Rico" in its constitution, as a translation into English of the term to "Estado Libre Asociado" (ELA).
