An open secret is a concept or idea that is "officially" secret or restricted in knowledge, but is actually widely known; or refers to something which is widely known to be true, but which none of the people most intimately concerned are willing to categorically acknowledge in public.
Famous quotes containing the words open and/or secret:
“With liberty and pleasant weather, the simplest occupation, any unquestioned country mode of life which detains us in the open air, is alluring. The man who picks peas steadily for a living is more than respectable, he is even envied by his shop-worn neighbors. We are as happy as the birds when our Good Genius permits us to pursue any outdoor work, without a sense of dissipation.”
—Henry David Thoreau (1817–1862)
“They are a very decent generous lot of people out here and they don’t expect you to listen.... It’s the secret of social ease in this country. They talk entirely for their own pleasure. Nothing they say is designed to be heard.”
—Evelyn Waugh (1903–1966)
