das Auto, -s

The German word "Auto" is a noun that refers to a "car". It is short for "Automobil", which in turn is derived from the Greek word "autos" (self) and the Latin word "mobilis" (movable). Thus, "Automobil" designates a self-moving vehicle. The word is used widely to refer to passenger cars.

Similar words would be "Fahrzeug" (vehicle), "Wagen" (wagon/car), or "Kraftfahrzeug" (motor vehicle). While all these terms can refer to a car, "Fahrzeug" is a more general term and includes all kinds of vehicles, including bikes and trucks. "Wagen" is somewhat informal and archaic but is still used similarly to "Auto." "Kraftfahrzeug" literally means motor vehicle and gives emphasis to motorization, referring to all motor vehicles.
