Poorer by的意思

"Poorer by" is an expression that means "less wealthy by" or "having lost money by." It is used to indicate a decrease in financial status or the amount of money one has. For example:

"After the stock market crash, he was poorer by $10,000."

This means that he had lost $10,000 and, as a result, was less wealthy than he was before the stock market crash. The expression can be used in various contexts to describe a financial loss or a decrease in wealth.
