Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
“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.
“Read the room” now means gauging a group’s mood or attitudes. HISTORY reports older wording with different room-inspection senses in 1896 and 1973, then a clearly modern social-cue use in a 1975 Oakland Post item quoted by the OED; those stages are kept separate.
“Keep Your Options Open” means to delay a final choice so that different possibilities remain available. The guide stays with current documented meaning and does not add unsupported origin chronology.
“Put Your Cards on the Table” means to be honest and open about your feelings, intentions, or position. This guide focuses on current documented usage and does not assert unsupported origin chronology.
“Fine print” refers to small-print terms or details that may contain important conditions; Cambridge notes that “small print” is the usual UK expression. The guide stays with current documented meaning and does not add unsupported origin chronology.
“Pull the strings” means to exercise control, often indirectly or secretly behind the scenes. It is distinct from “pull strings,” which can mean using influence to obtain help or an advantage.
“A taste of your own medicine” refers to treating someone in the same unpleasant way that they have treated others. Cambridge records both “dose” and “taste” in the established expression. This guide limits the page to current form and meaning and does not add an unsupported origin story.
“Hold Your Horses” means to tell someone to wait, slow down, or be less hasty. This guide focuses on current documented usage and does not assert unsupported origin chronology.
