My, how the times change. That definition used a word that is no longer allowed to be uttered in polite society. Perhaps that's why you printed the definition backwards -- but I'm sure someone, somewhere could still be offended (sigh).

John, the etymology of the word in question shows no connection to a racial slur, but thanks for sending me on an interesting google journey ... which, unfortunately no longer adds to my extensive trivia memory. 

Etymology - the study of the history of words  

Toponymy - the study of place names (toponyms), their origins, meanings, use, and typology.

typology - the study of symbolic representation, especially of the origin and meaning of Scripture types.
         

Perhaps we need a new word:

Emotology: the study of words that mean one thing but sound similar to words that offend Social Justice Warriors, and thus shouldn't be used in polite conversation ever again.
