Why is it more important to monitor your word choice in a professional environment than it is in

personal communications

In a professional settings, the people you are dealing will be most likely professionals who are important to your own business or for the company you work for. Also, they are not closely related people to you like friends or family, and could be coming from different backgrounds and different culture.

Because of this, we must be highly cautious and be considerate about the word choice when dealing in a professional context.
