The AVON and Trent are two rivers in Central England. The AVON is a four letter word and the Trent is a five letter word. Both rivers are major tributaries of the Severn, the longest river in the United Kingdom. The AVON rises in the Cotswolds and flows through the cities of Bristol and Bath before joining the Severn Estuary. The Trent rises in Staffordshire and flows through the Midlands before joining the Humber Estuary.
