River Trent
The River Trent is the third longest river in the United Kingdom, flowing for 185 miles through the North Midlands of England. It flows through the counties of Staffordshire, Derbyshire, Leicestershire, Nottinghamshire and Lincolnshire, forming a short part of that part of that county's border with Yorkshire, before entering the Humber estuary on the North Sea. It is the only major river in Great Britain to flow from South to North.
It traditionally forms the division between Northern and Southern England, along with the River Mersey, though geologists prefer to use the Tees-Exe line.
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.
