excerpt from George Orwell 'Politics and the English Language'

In prose, the worst thing one can do with words is to surrender to them. When you think of a concrete object, you think wordlessly, and then, if you want to describe the thing you have been visualizing, you probably hunt about till you find the exact words that seem to fit it. When you think of something abstract you are more inclined to use words from the start, and unless you make a conscious effort to prevent it, the existing dialect will come rushing inn and do the job for you, at the expense of blurring or even changing your meaning. Probably it is better to put off using words as long as possible and get ones meaning clear as one can through pictures or sensations.
