海上的漂流殘骸
這是字面的意思，也是其他用法借畫面的地方。
noun · C1
Pieces of a wrecked ship and of the things it was carrying — broken wood, boxes, rope — floating on the sea or left lying on the shore after the water has pushed them up.

核心畫面
One way to hold this word: a ship comes apart, and everything loose on it floats free. Planks, crates, rope. Nobody is holding them and nobody is steering them, so they go wherever the water goes, and end up wherever the water drops them. The word looks at that whole scatter at once, not at any one plank — which is why it never takes a or a plural.

可以想成一艘船在海上散掉之後的畫面。船上鬆掉的東西一件一件浮起來。木板、箱子、繩子都在水上。沒有人抓著它們，也沒有人決定它們往哪走。水流到哪，它們就到哪。最後被沖上沙灘，散在那裡。這個字看的是「這一整片散開的東西」，不是其中某一塊木板。所以它不可數，前面不加 a，後面也不加 s。後面兩個意思，都是把同一個畫面搬到別的地方用。From the word’s history
The word came into English from Anglo-Norman floteson and Old French flotaison, 'a floating', built on floter, 'to float' — the same family as float. So the oldest thing in the word is not the shipwreck; it is the floating.
這個字從古法文 flotaison（漂浮這件事）來，而 flotaison 來自 floter（漂浮），跟英文 float 同一家。所以字裡面最早的東西不是「船難」，而是「漂」。這正好解釋了為什麼三個意思都有同一種感覺：不是被人搬走的，是自己脫落、自己漂開的。
