Skeleton in the Closet
“A skeleton in the closet” means an embarrassing or damaging secret that someone wants to keep hidden. The expression is securely associated with early nineteenth-century print, but reviewed historical sources disagree over whether the key wording should be attributed to an 1815 work by Joseph Adams or to its 1816 appearance in The Eclectic Review.
It means a secret—often shameful or embarrassing—that could cause trouble if revealed. British English also uses “skeleton in the cupboard.”
Key details

Two specialist histories converge on the wording by 1815–1816, though they differ on attribution.
The phrase originated from doctors literally hiding illicit anatomy skeletons in cupboards.

Further guidance
Chronology boundary
The reviewed sources converge on very early nineteenth-century evidence but differ in attribution: Phrase Finder foregrounds the 1816 review, while World Wide Words traces the wording to Joseph Adams’s 1815 treatise as quoted in that 1816 review.
Meaning
Cambridge defines it as an embarrassing secret and notes the UK “cupboard” variant.
Origin boundary
The hidden-anatomical-skeleton story is not treated as established merely because it is vivid; reviewed specialist sources note the theory but do not establish it as the origin.
