Hello, I 've found that the Greek word ρατσισμός (racism) comes from the Italian razzismo < razza, which possibly comes from the Arabic ra's. (ra's: there was a sign like circumflex above a but I couldn't do that). I 've also read that there was suggested another etymology from the Latin ratio but it doesn't seem to be correct. Is really the first one accepted as correct? Is there any other? Thank you for any contributions!
