美国习语学习：you can't squeeze blood out of a turnip

帅哥朗读 English in a Minute。

Sometimes, American English does not make any sense. 

Like if someone says this: You can't squeeze blood out of turnip.

Let's see if we can figure out what it means...

You can't squeeze blood from a turnip means you cannot get something from a person that they don't have to give you. And it's used about money.

You see, it actually makes sense, because no matter how hard you squeeze a turnip, it will never bleed, and if somebody does not have any money to give you, you'll never be able to get it.
