Having clarified your objectives you need to check them against your perception of your reader's requirements and make sure that they match. In particular, you need to assess your reader's technical background so that your terms and concepts are appropriately presented. In much of the writing that you do, you will think that your reader already has a clear idea of what is the 'correct' response. Take this into account in your assessment of reader requirements, but do not allow it to dominate your work to the extent that it encourages you to write something that you either do not believe or do not understand. Choice of words Never fear big words.
Long words name little things.
All big things have little names such as life and death, peace and war, or dawn, day, night, love, home. Learn to use little words in a big way - it is hard to do. But they say what you mean. When you don't know what you mean, use big words. There is no recipe for writing first class prose.
