The word "stash" refers to a secret place where items, especially valuable or important ones, are stored or hidden away. It is often used when talking about keeping something safe, out of sight, or reserved for later use. The items in a stash can include money, food, or personal belongings.
The origin of the word "stash" can be traced back to the early 19th century. It is believed to come from the French word "estacher," which means "to place or position." The term evolved to represent the act of storing things away, particularly in a secretive manner.
