Language and offence (part 1)

David Cameron must have been taken aback earlier this week after an interview on Absolute Radio made the national news. Mr Cameron had used the same word which, a year ago, got children's author Jacqueline Wilson into trouble. A letter, it seems, can make a world of difference.

Those were trivial examples, but language does have the power to cause deliberate offence, and presumably that was the intention of Jonathan Ross in a reply to someone on Twitter recently.
