There's no single "other word" that perfectly replaces "Arab" and is universally accepted.
Here's why we should be cautious about using other terms:
* "Arabic" refers to the language: It's not a synonym for "Arab."
* "Middle Eastern" can be overly broad: It includes people from many different cultures and countries, not just Arab ones.
* Using the names of specific countries: This can be misleading as Arab people come from many different nations.
Instead of seeking a replacement, focus on using the term "Arab" respectfully and accurately.
