I’m always fascinated by words that are frequently misspelled and expressions that are widely misused. Some may blame the mistakes on shared ignorance, but I think there’s something more insidious at work. I think mistakes are contagious. People who see the words misused lack confidence in their own knowledge and mistakenly believe that what they already know must be wrong.
And why is it that store and restaurant owners invariably ask employees who suffer from that contagion to manage the changeable-letter signs in front of their businesses?
