Every Saturday I’ll give you a couple of idioms to learn. An idiom is a saying or phrase whose meaning cannot be taken from the literal meanings of the words.
bottom fall out/drop out: when the price falls below a previous lowest value.
Example:
A few years go the bottom fell out of the real estate market, and now many people owe more on their houses than what the house is actually worth.
tight spot: a dilemma, a difficult situation.
Example:
The customer put the salesman in a tight spot by insisting on an impossible time frame for delivery of the product.
