deadman
n.— Note: This term is covered in many mainstream dictionaries. «The church purchased an old school building, and member Gordon Ethridge moved it to the site on logs—with a little help from a “deadman,” Gatliff said. Another log, commonly called a deadman, was buried out ahead of the building and used as an anchor during the moving process. “They would pull it down to the deadman, then they would rebury it,” Gatliff explained.» —“Elam Baptist marks two centuries with book, celebration” by Rodney Manley Telegraph (Macon, Georgia) Aug. 2, 2008.
