Frequently Asked Questions

Why is 'break the bank' used to describe expensive things?

The phrase originates from gambling, where 'breaking the bank' meant winning all the money held by a casino, essentially depleting their funds. Today it means spending so much that you deplete your own financial resources.

Can these idioms be used in formal business communication?

Some, like 'cash cow' and 'go belly-up,' are commonly used in formal business contexts. Others like 'filthy rich' are more conversational. Context and audience determine appropriateness.
