I was looking for a term to define the eyes shape of oriental people and I discovered that the term slant-eye is a derogatory one:
- (offensive) a person with slanting eyes; especially , one of Asian ancestry
(MerriamWebster)
I checked its etymology and found that :
- Derogatory slang sense of "a slant-eyed Asian person" is recorded from 1943, from earlier slant-eyes (1929).
(Etymologyonline)
It seems that it was a neutral term at first but it became derogatory later. Is it so? What made the term sound offensive?
What alternative neutral expression can I use instead of "slanting eyes?
