One of the most important things to keep in mind is that your writing must be appropriate for your audience. You have to use terminology that makes sense to your readers.
When you become a professional in a particular field, you learn the language of that field. As a professional, people hire you to work on their behalf because you have knowledge and skills that they don’t possess. Therefore, you will often find yourself communicating in writing with people who don’t know the language of your field. Your writing has to make sense to the people who read it.
Chances are that several of the terms you just read don’t make any sense at all to you. When you write, you need to look closely at your messages, to make sure that you aren’t using terms that your readers aren’t likely to understand.
You know what you mean. Make sure your writing stands on its own, so that your readers will also know what you mean. That’s what good writing is all about.
