Person, People and Peoples
I know "people" is plural, but I was watching a movie and they said 'peoples'.
(Something like: ´they are vanishing' - 'what is vanishing?' - 'PEOPLES!')
It is a child movie, so my question is:
Is this 'peoples' thing something to give importance? or is it a slang? or is it a kids way to say people? or another thing? or just a mistake?
