Etymology is the study of the history of words. We should all take the time to make ourselves familiar with this branch of knowledge.
I believe that we should be more aware of the words we use. We should be mindful of our word usage due to the fact that it is contingent, to a certain extent, on the culture.
For example: I wouldn’t use the “N-Word” because it’s the word choice of many African Americans.
Awareness is key. To assure one is not committing appropriation, refer to the dictionary.
