C.S. Lewis’s last interview was on May 7, 1963—six months before he died. One of Sherwood Wirt’s questions was on writing: “How would you suggest a young Christian writer go about developing a style?”
The way for a person to develop a style is (a) to know exactly what he wants to say, and (b) to be sure he is saying exactly that.
The reader, we must remember, does not start by knowing what we mean. If our words are ambiguous, our meaning will escape him.
I sometimes think that writing is like driving sheep down a road. If there is any gate open to the left or the right the reader will most certainly go into it.

Seven years earlier (June 26, 1956), Lewis responded to letter from an American girl named Joan with advice on writing:
- 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 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.”
- In writing. Don’t use adjectives which merely tell us how you want us to feel about the things you are describing. I mean, instead of telling us the thing is “terrible,” describe it so that we’ll be terrified. Don’t say it was “delightful”; make us say “delightful” when we’ve read the description. You see, all those words (horrifying, wonderful, hideous, exquisite) are only like saying to your readers “Please, will you do my job for me.”
- Don’t use words too big for the subject. Don’t say “infinitely” when you mean “very”; otherwise you’ll have no word left when you want to talk about something really infinite.
