Answer:
If you use your language properly, you can maintain a connection between you and the reader. Eloquence, vividness, and understanding are what every reader needs.
You must use the language that everybody understands. In this case, the universal language (english).
Remember, your goal is to make your reader understand what he or she reads and to keep them interested in what you are writing. Write what you want to read. Write what your readers can understand.
