Word Nuance & Usage

In the United States, 'commonwealth' is the official title of four states (Kentucky, Massachusetts, Pennsylvania, and Virginia) and two territories (Puerto Rico and the Northern Mariana Islands), though the term carries no legal distinction from a standard state.

Word Origin & Etymology

Originating in the late 15th century as 'common weal', meaning 'public welfare' or 'general good', the second element was later altered to 'wealth' from Old English 'wela' (well-being) plus the suffix '-th'. It was popularized in the 16th and 17th centuries as an English translation of the Latin 'res publica' (republic).
