Mastering the Idiom: Break the Bank

Meaning: To spend a lot of money, often more than one can afford, on something. It usually suggests a significant financial outlay that could strain one's resources.

Origin: The idiom "Break the bank" originated from gambling, particularly in casinos, where winning a large amount of money could exceed the amount of cash reserves ("the bank") available to pay out winnings. In this context, "breaking the bank" means winning so much that it surpasses the casino's ability to cover the payout with available funds. Over time, the idiom has come to mean spending more money than planned or more than one can afford, often luxuriously or extravagantly. It emphasizes financial excess or surpassing typical limits, whether in gambling or everyday spending.
