Language evolves over time, and so too, does spelling. Such evolutionary changes can be and often are, misleading. From time to time in your reading you will surely happen upon phrases similar to these:
“The Great State of Wisconsin”
“The United States of America”.
In consideration of spelling changes over time you may find the above terms confusing. Perhaps a revision (or reversion, as the case may be) of simply adding an “e” or an “e” and an “s” might be of some assistance; thus:
(“The Great (e + state + s) of Wisconsin”)
(“The United (e + states) of America”)
“The Great Estates of Wisconsin”
“The United Estates of America”
This is offered in the sincere hope of clarifying your understanding of politics.
