Did you know?

English speakers started using flotsam, jetsam, and lagan as legal terms in the 16th and 17th centuries, with flotsam itself dating to the first years of the 17th. The three words were used to establish claims of ownership of the three types of seaborne, vessel-originated goods they named. Flotsam was anything from a shipwreck (the word comes from Anglo-French floter, meaning "to float"), and jetsam and lagan were items thrown overboard to reduce the cargo weight of a ship. Lagan was distinguished from jetsam by having a buoy attached so the goods could be found if they sank. In the 19th century, when flotsam and jetsam took on extended meanings, they developed synonymous applications and are today often paired, lagan having mostly been left at sea.
