Let the Cat Out of the Bag Meaning
Definition: To reveal a secret accidentally.
This idiom is used when one or more people learn new information that was meant to stay hidden or unknown. It is often used when someone shares the secret information verbally, but it can also be used when the information is discovered in other ways.
Origin of Let the Cat Out of the Bag
The origin of this saying is disputed, but the most common explanation is that it came from a trick that was used in the past in English market places.
Apparently, at an earlier time in history, baby pigs were often sold at market. The seller would give the buyer the piglet in a bag. As a trick to save money, the seller would sometimes stick a cat in the bag rather than a piglet. The buyer might not realize he had been cheated until the cat came out of the bag, and the trick was revealed.
