The word 'automobile' refers to a type of vehicle that people use for transportation, such as cars, trucks, and vans. It is a more formal word than 'car' and is often used in official documents or news reports. You can use the word 'automobile' when you are talking about the broader category of vehicles, or when you want to sound more formal, but it is not necessary to use it in everyday conversation. In most situations, it is enough to say 'car' or 'vehicle' instead.
