Not only did Abraham Lincoln pioneer the use of "sugarcoat" in the sense of making something bad seem more attractive or pleasant, but he stirred up a minor controversy with the word, too.
In 1861, four months after he was inaugurated, Lincoln wrote a letter to Congress as Southern states were threatening to secede from the Union.
"With rebellion thus sugar-coated they have been drugging the public mind of their section for more than 30 years, until at length they have brought many good men to a willingness to take up arms against the government," Lincoln wrote, according to Dickson.
John Defrees, in charge of government printing, was so incensed by Lincoln's folksy verbiage that he admonished the president, telling him, "you have used an undignified expression in the message."
But Lincoln insisted on using the word "sugarcoat," and he got the last laugh: "That word expresses precisely my idea, and I am not going to change it," he responded. "The time will never come in this country when the people won't know exactly what 'sugar-coated' means."
