Definition of the word trolley

The word "trolley" has an interesting origin. It comes from the Greek word "trollein," which means "pulley" or "drag." In the late 18th century, the term "trolley" referred to a type of pulley system used on ships to lift and move heavy loads. In the mid-19th century, the term "trolley" was adopted in the United States to describe a type of electric car that ran on tracks, often used for transporting people or goods in cities. The term was likely chosen because of the pulley-like wheels on the car's axles. Over time, the term "trolley" became widely used to describe public transportation systems, including streetcars, buses, and even grocery carts towed behind a handle. Today, the word "trolley" is used around the world to refer to various types of vehicles or carts that run on tracks or wheels.
