"new" is not a prefix. there is no US state called New-York, NewYork, New-Hampshire, NewHampshire and so forth. The case of the missing hyphen and the missing concatenation.
Oh this is a forum for questions. So my question is:
Who gives a s***t how many states there are in the USA with the prefix "New"?
For that matter, how many counties does england have?
How many states are there with the prefix "New" in the USA ?
None
