Cách sử dụng
The phrase "cut the ground from under somebody's feet" means to take away someone's power or advantage, often suddenly and unexpectedly. It's like pulling a rug out from under their feet, leaving them unbalanced and without support. You might use this expression when someone is relying on something to help them succeed or achieve something, and you take it away, causing them to fail or struggle. For example, if a friend is planning to apply for a job you want, you could apply first and "cut the ground from under their feet" by getting the job before they can.
