infamy - IN-fah-MEE - shame, disrepute, disgrace, notoriety
Example: "When FDR referred to the Pearl Harbor attack as a 'day of infamy,' he could have been saying the same about the day we honor today - our sadly recalled day of infamy."
As a starter: and as a former teacher in English, I hope to add to reader's vocabulary by presenting a word a day in simple terms that anyone can understand - from current use in publications, radio,TV, etc. Remember: use a new word three times in a day and it's yours forever!
