“A stone’s throw” is a phrase that refers to a very short distance. It is used to describe a place or object that is very close by, and can be easily reached or accessed.
The phrase is believed to have originated in ancient times, when people used to measure distances by throwing stones. If a place was close enough that a stone could be thrown to it, it was considered to be “a stone’s throw” away.
Today, the phrase is used more generally to refer to any short distance, and is often used to describe a place that is within easy walking distance or a short drive away. It is a way of saying that something is very close by, and can be easily reached or accessed.
Example: The hotel was a stone’s throw from the beach. I loved it.
