“Always try to use the language so as to make quite clear what you mean, and make sure your sentence couldn’t mean anything else.”
“Always prefer the plain direct word to the long, vague one. Don’t say implement promises, but keep them.”
Never use abstract nouns when concrete ones will do. If you mean ‘more people died,’ don’t say ‘mortality rose.’
“Don’t use adjectives which merely tell us how you want us to feel about the thing you are describing.” Under this heading, Lewis goes on to say that the writing should delight readers, not just label an event delightful; or it should make them feel terror, not just to learn that an event was terrifying. He says that emotional labeling is really just a way of asking readers, ‘Please, will you do my job for me?’
“Don’t use words that are too big for the subject.” Lewis illustrates this point by saying if you use infinitely as an intensifier instead of the simple word very, you won’t have any word left when you need to describe something that is truly infinite.
