flotsam
FLOT-sum
Wreckage or cargo floating on the sea after a shipwreck — the debris that finds its own way to shore. Legally distinct from jetsam, which is deliberately thrown overboard. Flotsam is what the sea takes; jetsam is what you give it.
Etymology
Anglo-French: floteson, from Old French floter (to float). Related to English fleet and float.
