River Stour, Suffolk

The River Stour (/ˈstʊər, ˈstaʊər/)[1] is a river in East Anglia, England. It is 47 miles (76 km) long[2] and forms most of the county boundary between Suffolk to the north, and Essex to the south. It rises in eastern Cambridgeshire, passes to the east of Haverhill, through Cavendish, Bures, Sudbury, Nayland, Stratford St Mary, Dedham and flows through the Dedham Vale Area of Outstanding Natural Beauty. It becomes tidal just before Manningtree in Essex and joins the North Sea at Harwich.

The name is of ambiguous and disputed origin.

On one theory, the name Stour derives from the Celtic sturr meaning “strong”.[3] However, the river-name Stour, common in England, does not occur at all in Wales;[4] Crawford noted two tributaries of the Po River near Turin, spelled Stura. In Germany the Stoer is a tributary of the River Elbe. According to Brewer’s Britain and Ireland the Stour is pronounced differently in different cases: the Kentish and East Anglian Stours rhyme with tour; the Oxfordshire Stour is sometimes rhymes with mower, sometimes with hour, and the Worcestershire Stour always rhymes with hour.[5] Locally, the River Stour dividing Essex from Suffolk does not have a uniform pronunciation, varying from stowr to stoor.[6]

As against that, stour is a Middle English word with two distinct meanings and derivations, still current enough to appear in most substantial dictionaries. As an adjective, with Germanic roots, it signifies “large, powerful” (in present-day Scandinavian languages stor means “big, great”). As a noun, from medieval French roots, it signifies “tumult, commotion; confusion” or an “armed battle or conflict”. Wiktionary also adds “blowing or deposit of dust”, the primary definition in the Concise Oxford Dictionary, which adds that this is a northern English and Scottish usage of uncertain derivation.[7] In 2006 it has been suggested that an Old European river-name was taken for an Old English adjective and that stour came to represent one pole of a structural opposition, with blyth at the opposite pole, allowing Anglo-Saxons to classify rivers on a continuum of fierceness.[8]
