I've always seen it as so in my own head, although probably not correct- List below starting from East to West.

Eastern Lands- Asian. Japanese comes up as #1 in my mind

Mieyrditch- Russian

Burgh De Rot- Romanian

Canifis- Polish

Varrock/Barbarian Village- German

Lumbridge- Irish

Al-Kharid- Middle Eastern/Iranian

Draynor Village- Scotland

Edgeville- Eh...

Falador- English

Port Saramin- English

Rimmington- English

Taverly- Irish

Burthope- Swiss

Catherby- Ehh.. Belgian?

Camelot/Seers- Luxembourgish

Fremmenik Areas- Scandinavian

Ardouge/Area around it- French

Yanille- Italian

Elf places- Welsh

Of course, there were more. But that's what I could think of. Again, this is what I have interpreted myself and is more than likely incorrect than what Jagex had intended.
