Old-chestnut Definition

Origin of Old-chestnut

• A commonly cited theory, viewed by the Oxford English Dictionary as “plausible” and cited by Brewer’s, is that it was coined by Boston comedic William Warren Jr., quoting from 1816 English melodrama The Broken Sword by William Dimond. One of the characters in the play is a boor, and when once recounting a tale mentions a cork tree, which is corrected by the character Pablo as “A chestnut. I have heard you tell the tale these 27 times.” This line was then apparently quoted at a dinner party by Warren in response to a boor there, and proved popular. Note that William Warren Sr. had previously played Pablo on stage, but died in 1832, so the phrase was presumably popularized by the son, William Warren Jr.
