The phrase 'A Blessing in Disguise' refers to something that at first appears to be bad or unlucky but is actually good.
Example of Use: "My car broke down again, but maybe it was a blessing in disguise; I've been wasting too much time driving around anyway."
The origin of the idiom 'a blessing in disguise' is believed to be mid-1700s, however scholars have yet to pin down the first usage of the term. The earliest instance of the term found in print was a 1746 work by English writer James Hervey titled Reflections on a Flower-Garden. There is no evidence that he coined the phrase.
