The word "sentinel" originates from the Latin word "sentina", which originally referred to a container for storing edible supplies on a ship. Over time, the word evolved to refer to a person assigned to guard or watch for dangers or intruders, particularly in military contexts. This transition in meaning likely occurred due to the practice of assigning individuals to stand guard near the ship's stored supplies to protect them from theft or spoilage. The term eventually entered into the English language, and "sentinel" has since come to signify a vigilant person or a guard responsible for surveillance and protection.
