Are there any rules governing what we call people from different countries?
In the English language, you have several endings used when you construct an adjective out of the name of a nationality. For example, the nationality of Japan is Japanese while the nationality of Korea is Korean.
Is there a grammar rule that decides what ending should be used? Or what did decide on what ending to use?
And is the -nese ending connected to Polynesia somehow? As the -nese endings seem concentrated in that area?
