Are there any rules governing what we call people from different countries?
I have some confusion regarding usage of suffixes such as -ites / -ians / -ish.
I have seen some people using the words Kerelite and Mumbaites for people from Kerela (a state) and Mumbai (a city).
Indians (where India is a country)
Spanish (Where Spain is again a country)
So on what basis do we decide what suffixes should be used, or is it very dependent on mood or environment?
