Q. How can I look up words like “illegal alien” or “lady” that are hurtful to the people described?
A. Use search terms like “bias-free writing,” “slurs to avoid,” or “offensive terms.” To find general advice on how to write sensitively, you can search for “inclusive language” or “conscious style.” CMOS 5.251–60 (on bias-free language) might help. You can also find lots of advice at Conscious Style Guide.
