Do you say gooseberries or goosegogs? Would you call someone hen, my luvver or me duck? Do you like to eat a cob, butty or just a plain sarnie? And do you know what a grockle is? Using material from the BBC's ground-breaking Voices survey, "Talking for Britain" explores regional English in the twenty-first century, painting a vivid portrait of the British people and uncovering fascinating facts about local language. We may think that English is becoming homogenized as words such as chav and knackered spread across the country, but there is still surprising regional variation. How, for example, would you describe someone who is a bit moody? In Barrow-in-Furness, you might say that they are narky, while in the Midlands, they're probably mardy. In Scotland, they might be crabbit, but in Northern Ireland, they could well be feeling distinctly thrawn. A fascinating and superbly browsable book, "Talking for Britain" proves that regional English is very much alive and well - and constantly changing.
