A carriage is a wheeled vehicle for people, usually horse-drawn; litters (palanquins) and sedan chairs are excluded, since they are wheelless vehicles. The carriage is especially designed for private passenger use, though some are also used to transport goods.
A public passenger vehicle would not usually be called a carriage – terms for such include stagecoach, charabanc and omnibus. It may be light, smart and fast or heavy, large and comfortable or luxurious. Carriages normally have suspension using leaf springs, elliptical springs (in the 19th century) or leather strapping.
Working vehicles such as the (four-wheeled) wagon and (two-wheeled) cart share important parts of the history of the carriage, as does too the fast (two-wheeled) chariot.
The word carriage (abbreviated carr or cge) is from Old Northern French cariage, to carry in a vehicle. The word car, then meaning a kind of two-wheeled cart for goods, also came from Old Northern French about the beginning of the 14th century (probably derived from the Late Latin carro, a car);
it was also used for railway carriages, and was extended to cover automobile around the end of the nineteenth century, when early models were called horseless carriages.
A carriage is sometimes called a team, as in “horse and team”. A carriage with its horse is a rig. An elegant horse-drawn carriage with its retinue of servants is an equipage. A carriage together with the horses, harness and attendants is a turnout or setout. A procession of carriages is a cavalcade.
