Without clarity there is no real communication. If you want to communicate clearly, the first thing you have to do is to put yourself in the position of the audience. How much, if anything, do they know about the subject you are going to tell them about? Who are your audience - for instance, if you are going to talk or write about a scientific subject, will they understand the technical words you use or should you explain the terms?
A good way to test the clarity of your writing, speech or whatever is to try it out on someone you know who is not a specialist in that subject. Let him or her give you a quick summary of your topic after reading or hearing it. If they can't, it may be time for you to look at the way you explain things.
Last tip -don't forget visual information. If you have a chance to use illustrations, graphs etc as well, it's always a good idea to do that.
