Is it a wreck, a tree or an oyster egg?

According to the Oxford English Dictionary:

In law, flotsam or floatsome is strictly that part of the wreckage of a ship or its cargo as is found floating on the surface of the sea.

However, in dialect use floatsome can also mean timber, etc. accidentally carried down a river by a flood.

Also in dialect floatsome is newly ejected oyster-spawn.

Complicated thing the English language. I'm glad that I am not learning it from scratch. Having said that, I've still got a staggering lot left to learn. Trouble is, these days I seem to forget faster that I learn!
