Lately, it seems like you need to feel guilty using words that have more than two syllables. People start thinking that you trying to show off and they might accuse you of being pedantic.
Now comes American Heritage Dictionary listing their top ten words that each high school graduate should know. It reminded me that I shouldn't feel sorry for using words that are more precise, closer to the intended meaning. But, will people understand what I'm trying to say because they don't know the words.
