You must keep your language clear and simple so that your readers or listeners can understand.
Sentences should be short - no longer than 20 words or three concepts (ideas). Sentence structure should be simple; it is best to write in the active voice.
Explain any new words whenever you use them.
Avoid jargon, unnecessary words and clichés.
Check all your work to make sure that everything you write obeys the rules of grammar and punctuation.
When translating, translate the meaning of sentences, not the individual words.
Always keep your readers or listeners in mind whatever you write.
