1) Simplicity: Use Small Words

Via Words That Work: It’s Not What You Say, It’s What People Hear:

“Avoid words that might force someone to reach for the dictionary… because most Americans won’t. They’ll just placidly let your real meaning sail over their heads or, even worse, misunderstand you. You can argue all you want about the dumbing down of America, but unless you speak the language of your intended audience, you won’t be heard by the people you want to reach.”

2) Brevity: Use Short Sentences

Via Words That Work: It’s Not What You Say, It’s What People Hear:

“Be as brief as possible… The most memorable political language is rarely longer than a sentence. “I Like Ike” was hardly a reason to vote for the man, but the simplicity of the slogan matched the candidate and the campaign.”
