On one theory, the name "Stour" derives from the Celtic "sturr" meaning "strong". However, the river-name "Stour", common in England, does not occur at all in Wales; 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". Locally, the River Stour dividing Essex from Suffolk does not have a uniform pronunciation, varying from "stowr" to "stoor".
