The River Trent is one of England's largest rivers. It flows through the counties of Staffordshire, Derbyshire, Leicestershire, Nottinghamshire and Lincolnshire, before entering the Humber Estuary, on the North Sea. It is the only major river in Great Britain to flow from South to North.
As with many river names in England, the name Trent is of British (Celtic) origin. It comes from the British Trisanton, which may approximately be translated as 'trespasser' and in this sense used of a river liable to flood.
