The Oxford English Dictionary (OED) should no longer be the main authority on the English language because it does not keep pace with today’s rapid linguistic changes, a report said on Thursday. Left-wing think-tank Demos said the OED should be replaced by a website – democtionary org – that would allow English-speaking members of the public from Britain and abroad to contribute their own words and definitions.The report’s co-author, Sam Jones, said an online dictionary similar to the user-generated Internet encyclopaedia Wikipedia was needed to track the pace of language change and the influence of non-native speakers on it. Chief editor John Simpson welcomed Demos’s contribution, but denied the OED was a prescriptive rather than a descriptive reference work.
