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:
“... possibly there is no needful occupation which is wholly unbeautiful. The beauty of work depends upon the way we meet it—whether we arm ourselves each morning to attack it as an enemy that must be vanquished before night comes, or whether we open our eyes with the sunrise to welcome it as an approaching friend who will keep us delightful company all day, and who will make us feel, at evening, that the day was well worth its fatigues.”
—Lucy Larcom (1824–1893)
“The Frost performs its secret ministry,
Unhelped by any wind. The owlet’s cry
Came loud—and hark, again! loud as before.”
—Samuel Taylor Coleridge (1772–1834)
