A caravan can refer to two different things:
-
A group of people and animals or vehicles who travel together for safety through a dangerous area, especially across a desert on camels. This can also refer to a group of vehicles traveling together.
-
A trailer towed behind a road vehicle to provide a place to sleep which is more comfortable and protected than a tent. Caravans can vary from basic models which may be little more than a tent on wheels to those containing several rooms with all the furniture and furnishings and equipment of a home. They are used principally in North America, Europe, Australia, and New Zealand.
In summary, a caravan can either refer to a group of people or vehicles traveling together for safety or a trailer towed behind a road vehicle to provide a place to sleep.
