Coterminous: two things sharing the same borders. In the USA this normally applies to major cities and the counties in which they reside. For example, the borough of Manhattan is coterminous with the (largely defunct) county of New York. I believe the same is true of Chicago and Cook County.
Do you know of any coterminous things? I would love to find some more!
Edit: I learned two interesting ones in Hawaii. The county of Hawaii is coterminous with "The Big Island" of Hawaii, which makes sense. Also there's a village called Kalawao which is its own county due to its history of being a leper colony at some point in the past!
Oh fuck, you mean I'm in BOSTON?!
the fact that there are two Suffolk County's one hundred miles apart really says something
kinda like the number of Blount County's in Tennessee and Alabama
and I only heard this second-hand and can't back it up, so take this for a grain of salt
the East Tennessee Human Resource Agency, which handles services from housing to employment to public transportation, had the idea to launch a government website for looking up information and handling certain tasks through a web form
and they very nearly called it YourETHRA.
