把錢從人身上挖走
同一個挖的動作，換了對象：被挖走的不是木料，而是別人口袋裡的錢。這是一個比喻，不是另一條歷史來源。

To make someone pay a price that is far too high, or to cheat them out of money, especially when they have no other place to go.
敲竹槓
核心畫面
Hold a curved blade against a piece of wood, push, and turn. A piece of the wood comes away and a rounded hollow is left behind. That one movement is the whole word. The tool with the curved edge is a gouge, the movement is to gouge, and the hollow left behind is a gouge as well - English lets one word be the tool, the act and the mark. The thing to keep hold of is that something is always taken away. That is why a gouge is a hollow you can put a fingertip into and not a thin line on the surface, and it is also why the word works on money.
可以想成把一把彎口的刀貼在木頭上，往前一推，再一轉。一塊木料被挑起來，留下一個圓弧形的凹。整個字就是這一個動作。刀口…更多收起
可以想成把一把彎口的刀貼在木頭上，往前一推，再一轉。一塊木料被挑起來，留下一個圓弧形的凹。整個字就是這一個動作。刀口彎彎的那把工具叫 gouge，做這個動作叫 gouge，留下來的痕跡也叫 gouge——英文讓同一個字同時當工具、動作和結果。要記住的重點是：一定有東西被挖走了。所以 gouge 是一個手指摸得進去的凹，不是表面一條線；也正因為「挖走」這件事，這個字後來能用在錢上。From the word’s history
From Middle English gouge, from Old French gouge, from Late Latin gubia, a chisel or piercer, borrowed from Gaulish and going back to a Celtic word for a beak or bill. The old meaning is the picture: a curved beak driven into something and lifting a piece away.
經中古英文 gouge、古法文 gouge，上溯到晚期拉丁文的 gubia（鑿子、穿刺的工具），再往前是高盧語，源頭是凱爾特語裡表示「鳥喙」的字。最早的意思就是這個畫面：一張彎彎的喙啄進去，把一塊料挑起來。
