George Orwell gives these tips:
# Never use a metaphor, simile or other figure of speech which you are used to seeing in print.
# Never use 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.
