Possible Duplicates:
“People” or “peoples” when referring to an indigenous population?
Person, Persons, People, Peoples

I've seen someone using the word "peoples" today, with a vehement claim that it "is NOT grammatically incorrect". I searched on the net, but I got links (such as this) which suggests it is correct. Either way, is there a reference which could settle this issue ?

Best Answer

This is an entry from OALD online:

3 [countable] all the persons who live in a particular place or belong to a particular country, race, etc

the French people

the native peoples of Siberia

So, when used in this sense, the word "people" has a plural form and it is grammatically correct.
