BBC NEWS | The Editors:
"Each week on Newswatch (http://news.bbc.co.uk/newswatch/ukfs/hi), complaints come and go from members of the public about what some see as mistaken news priorities, bias, inaccuracy, or trivialisation. But what remains constant, and what seems to elicit the ire of viewers more than anything else, is one topic: sloppy grammar. Everyone seems to have their personal bugbear, be it the use of 'less' instead of 'fewer', the split infinitive, or the use of a plural noun with a singular verb. And many feel that standards have slipped in recent years.
We thought we'd put this to the test, and invited a number of BBC journalists to demonstrate their grammatical expertise - or otherwise - on camera. Perhaps surprisingly, five presenters or correspondents were brave enough to take up the challenge: spotting 20 deliberate grammatical errors which we'd inserted in a mock conversation between a presenter and a correspondent."
