North or northern
It’s a wonderful blog. Congratulations!
I’m in this predicament:
What is the rule for using north/south/east/west and northern/southern/eastern/western with geographical names?
For example, why is it called “Eastern Europe” instead of “East Europe” and “North America” instead of “Northern America”. In this regard, which collocation is more acceptible - “Southern France” or “South France”. Why? What’s the rule?
