I’ve always loved the word “mellifluous.” It’s a lovely example of onomatopoeia—words that suggest or imitate the thing they are describing. On the other hand, I physically itch when someone says “chafe.” It’s far more irritating than, say, “irritating.”
Since our goal is to influence our readers, corporate writers need to be especially sensitive to word choice. I recently saw a job search letter in which the applicant described her work as “superior.” The word gave me a mental image of the woman looking down her nose at her colleagues. The same applicant wrote that she had a “chronic” interest in magazine writing. She would have been better off with “continuing” (although the urge to write does sometimes feel like a disease).
