WVU's examples are fitting, but I'll add heinous, barbaric, despicable, and abominable as options. As WVU said, it's probably better to remove the pretense and use words we all know.
I'm always looking for an opportunity to post this, so now seems like a good time.
Rules for writing by George Orwell:
- Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.
- Never us a long word where a short one will do.
- If it is possible to cut a word out, always cut it out.
- Never use the passive where you can use the active.
- Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
- Break any of these rules sooner than say anything outright barbarous.
For the fiction writers, here's a list by Kurt Vonnegut:
- Use the time of a total stranger in such a way that he or she will not feel the time was wasted.
- Give the reader at least one character he or she can root for.
- Every character should want something, even if it is only a glass of water.
- Every sentence must do one of two thingsreveal character or advance the action.
- Start as close to the end as possible.
- Be a Sadist. No matter how sweet and innocent your leading characters, make awful things happen to themin order that the reader may see what they are made of.
- Write to please just one person. If you open a window and make love to the world, so to speak, your story will get pneumonia.
- Give your readers as much information as possible as soon as possible. To hell with suspense. Readers should have such complete understanding of what is going on, where and why, that they could finish the story themselves, should cockroaches eat the last few pages.
