Fortunately, we know who made this term and the occasion upon which he first used it. Noah Webster, the famous dictionary maker, coined demoralize. Although he spent fifty years of his life studying words and defining them in dictionaries, this is the only one he ever made. In 1794 he wrote about the French Revolution, and in this he emphasized the bad effects of war, especially civil war, on the morals of the people involved. He referred to these effects as demoralizing.
Webster knew he had added a word to the language. He watched to see if others would adopt it, and was pleased to see that the term soon became popular. Before he died in 1843 he knew demoralize had become firmly established in the language.
His word has had an unusual thing happen to it. As soon as people began to notice the term, some of them supposed Webster had borrowed it form the French word demoraliser, but in a dictionary he brought out in 1828 Webster explained he had made it by placing the common prefix de on moralize or moral. And this explanation he stuck to as long as he lived.
Not long after his death, however, his word was explained as being derived from French, and some dictionaries still give this explanation of it. How does your dictionary say demoralize originated?
