Negro, simply meaning black in Spanish, had to be discarded by those of Jackson’s ilk because it was used during the slave era. It wasn’t the only name used then for blacks, but it was the most polite.

Thank G_d we don't call em what the Arabs do.

Abdl translates as the same word ~ slave / black.

Actually “Colored” was the most polite, but back when I was in grade school, the three prominent races were: Caucasian, Negroid, and Mongoloid.
Every area of the world, including the US, had their own derivations. My grandmother in Atlanta used the term “Nigra”, and it was not in a derogatory way.
Some, but not all, were considered degrading.
