Basically, Latin version of Greek version of Phoenician.
England is particularly good (if that's the right word) at these but it's not alone. If you're from Buenos Aires then you're a Porteño (because it's a _port_). If you're from Christchurch then you're a Cantabrian (because of a historical association with Canterbury in the UK). If you come from Rio de Janeiro then you're a Carioca (from the name of a tribe that lived there before the Portuguese invaded).
Since English has chronic trouble mapping sounds, especially vowels, that are fundamental for Russian, ‘Muscovy’ is in fact a rather reasonable approximation. ‘Moscovia’ would be better, but alas. It's like we're seeing different fundamental colors―which we sort of do with English ‘indigo’ and Russian ‘light-blue’ (the latter being close to Newton's ‘blue’).
> Newton divided his color circle, which he constructed to explain additive color mixing, into seven colors. His color sequence including the tertiary color indigo is kept alive today by the Roy G. Biv mnemonic. Originally he used only five colors, but later he added orange and indigo to match the number of musical notes in the major scale.
So, the concept of there being uniquely-important indigo (and orange!) points on the hue spectrum were just, kinda... made up, as a bit of numerological whimsy, by Isaac Newton. And everyone else in the Western world just followed his lead, because he seemed to know what he was talking about.
I would note that no English-speaker actually seems to describe anything as “indigo” in practice. People do tend to describe plenty of things as “light blue”, though! We get taught “ROY G BIV” in kindergarten, but we basically ignore it, because it doesn’t actually fit anything else we get taught. (I don’t even recall any children’s picture books that bother with examples of “indigo” objects.)
IMHO, there’s also a much more fundamental distinction made in English-in-practice, between three kinds of green: yellow-green (“spring green”, “olive green” when desaturated), “green green”†, and blue-green (“sea blue”, cyan, turquoise.) Many people will insist that, if orange is a separate color from yellow or red, then yellow-green and green-blue are separate colors as well.

Quote of the day:
"poems by the Anglo-Saxon scholar the Venerable Bede translate more successfully into Geordie than into Standard English"
The Venerable Bede will for evermore have a Geordie accent.
I also like to call people for Norfolk, Norfolk (as in folk), I don't think that's standard though.
These ditches are called Punic not because they were invented by the Carthaginians (Punic is the adjective for things from Carthage, don't ask me why), but because they were incredibly brutal, and Rome's early wars with Carthage were so horrific, they became a byword for anything eye-wateringly cruel like this.
