This noun denotes jettisoning cargo or throwing things overboard from a ship, typically to lighten the vessel in storms. In Acts 27:18, during Paul's storm-tossed voyage, 'they made a jettisoning' by throwing cargo overboard. The term comes from the verb 'to throw out' and classical usage confirms it meant jettisoning cargo, though it could also mean unloading, expulsion, or even divorce. The multilingual evidence (Spanish 'descarga' = unloading, French 'naufrage' = shipwreck, English 'jettisoning') shows varied approaches to this nautical emergency measure.
