The Origin of Jettison

Jettison comes from Anglo-French geteson, which means literally "action of throwing" and is related to the Latin verb jactare, meaning "to throw." The noun jettison refers to a voluntary sacrifice of cargo to lighten a ship's load in time of distress, and it is the source of the word jetsam (the name for goods "jettisoned"); the word is often paired with flotsam ("floating wreckage"). These days you don't have to be on a sinking ship to "jettison" something: the verb also means simply "to get rid of."
