By some accounts, the first part of the name was derived from an historical association with the Huns, and the second from a Latinized form of Byzantine Greek, "Oungroi." Another possibility is that the name was derived in medieval times from the name of the people, "ungari" or "ungri."
1. The equator isn't often known as *the* great circle. It is, however, recognised as being *one* of the various great circles. (A great circle is the largest-possible circle that can be drawn on a sphere. e.g. all of the Meridians are also great circles.)
2. Clues about the equator also apply to Equatorial Guinea.
Thanks for the nice comment. Re: Ecuador, hence the "sometimes." I can't think of any other country that would qualify, should provide enough info to get it. At least if you know a bit of Spanish.
I thought there was evidence that the name "America" didn't come from Amerigo due to maps having America on them before his association with it. The theory is that America comes from a Central American Tribe called the "Amerique" or something similar to that. Also, the name Hungary doesn't come from the Huns but rather only from the Greek word shown in the description who's Latin translation is "Ungri".
N.B. for the Ecuador question:
1. The equator isn't often known as *the* great circle. It is, however, recognised as being *one* of the various great circles. (A great circle is the largest-possible circle that can be drawn on a sphere. e.g. all of the Meridians are also great circles.)
2. Clues about the equator also apply to Equatorial Guinea.
Even if that wasn't the intent, "DRC" and "Congo" should still be accepted answers.
